Is the Volume gas directly proportional to its molecular weight?
No, the volume of a gas is not directly proportional to its molecular weight. The volume of a gas is mainly influenced by the number of gas molecules present, temperature, and pressure. The ideal gas law equation, PV = nRT, takes into consideration these factors to describe the relationship between volume, pressure, temperature, and the amount of gas.
How does depths affects fluid pressure?
Fluid pressure increases with depth due to the weight of the fluid above pushing down. This relationship is described by the hydrostatic pressure equation, which states that pressure is directly proportional to depth. As depth increases, the weight of the fluid column above increases, resulting in higher pressure at greater depths.
What is the principle of osmometry?
Osmometry is a technique used to measure the osmotic pressure of a solution. It is based on the principle that the number of particles in a solution contributes to its osmotic pressure, which can be used to calculate the molecular weight of unknown solutes.
How quickly gas spreads in air?
The diffusion rate of gas in air depends on factors like temperature, pressure, and molecular weight of the gas. Gases with lower molecular weight tend to diffuse faster than those with higher molecular weight. In general, gas molecules will spread throughout the air relatively quickly due to their high mobility and ability to mix freely.
What is the freezing point of a substance with a molecular weight of n2?
The freezing point of a substance with a molecular weight of N2 is -210.01 degrees Celsius.
What is the molecular weight of a compound with pressure 750mm Hg volume 275ml weight 0.920g and temperature of 100c?
In order to find the molecular weight of a compound the components would have to be converted. The conversions are 750mmHg to .987atm, 275ml to .275l, the weight stays at .920g, and the temperature from 100c to 373.15k. These numbers plugged into the equation MW=mRT/(PV) the molecular weight is found to be -.63.
Is the Volume gas directly proportional to its molecular weight?
No, the volume of a gas is not directly proportional to its molecular weight. The volume of a gas is mainly influenced by the number of gas molecules present, temperature, and pressure. The ideal gas law equation, PV = nRT, takes into consideration these factors to describe the relationship between volume, pressure, temperature, and the amount of gas.
What is the equation of baromatric pressure?
The equation for barometric pressure is often expressed using the hydrostatic equation, which relates pressure and altitude. It can be represented as ( P(h) = P_0 e^{-\frac{h}{H}} ), where ( P(h) ) is the pressure at height ( h ), ( P_0 ) is the sea level pressure, and ( H ) is the scale height, which depends on temperature and the molecular weight of the air. In a more detailed version, the equation can also take into account temperature variations and humidity.
How do you calculate number average molecular weight given molecular weight range and fraction?
To calculate the number average molecular weight, multiply each molecular weight value within the range by its corresponding fraction, then sum up these products. This sum represents the numerator of the equation. Next, sum up all the fractions in the denominator. Finally, divide the numerator by the denominator to obtain the number average molecular weight.
How molecular weight and sedimentation constant is related to each other?
Molecular weight and sedimentation constant are related through the Svedberg equation, which states that the sedimentation constant (S) is inversely proportional to the molecular weight of a molecule. This means that larger molecules with higher molecular weights will have lower sedimentation constants, while smaller molecules with lower molecular weights will have higher sedimentation constants.
Chlorine diffuses 2.04 faster than gas Q Find molecular weight of gas Q?
To find the molecular weight of gas Q, we can use Graham's law of diffusion. The rate of diffusion is inversely proportional to the square root of the molecular weight. Since chlorine diffuses 2.04 times faster than gas Q, we set up the equation (rate of Q)/(rate of Cl2) = sqrt(Molecular weight of Cl2 / Molecular weight of Q), then solve for the molecular weight of gas Q.
A gas exerts a pressure of 0.892 ATM in a 5.00 L container at 15 degrees Celsius The density of the gas is 1.22 gL What is the molecular weight of the gas?
The ideal gas law equation is used to find the molecular weight: PV = nRT. Rearranging for molecular weight, we get MW = (mRT)/(PV), where m is the mass of the gas in grams, R is the ideal gas constant, T is temperature in Kelvin, P is pressure in ATM, V is volume in Liters. First, calculate the mass of the gas using density: m = density * volume = 1.22 g/L * 5.00 L = 6.1 g. Then plug in the values for pressure (0.892 ATM), temperature (15°C = 288 K), volume (5.00 L), and the calculated mass (6.1 g) into the rearranged equation to find the molecular weight.
How do you find molecular mass if specific volume is given?
To find the molecular mass if specific volume is given, you can use the ideal gas law. The ideal gas law relates the pressure, volume, temperature, and the number of moles of gas to the gas constant. By rearranging the ideal gas law equation and solving for the molecular mass, you can determine the molecular mass of the gas.
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
What is the number of apples in 0.25 moles of apples?
The question does not contain enough information. The equation is number of moles = mass (of compound) / molecular mass of compound. You do not know the weight of an apple (cannot get one specific figure for this), nor does an apple have a molecular weight
What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
