Compare the rate of effusion of hydrogen and helium?
c) Helium effuses 2 times faster than hydrogen. Its like the apple A5 chip which is up to twice as fast as the A4 chip.
How do you calculate the ratio of effusion rates for nitrogen times two and neon?
use the formula: the square of (RT3)/molar mass in kilograms
The molar mass of argon is 40 gmol. What is the molar mass of a gas if it effuses at 0.91 times the speed of argon gas?
graham's law (Rate 1 / rate 2) ^2 = MM2 / MM1 (Rate x / rate Ar) ^2 = MM Ar / MM x (.907)^2 = 39.9481 / MMx MMx = 39.9481 / 0.8226 Molar mass of unknown gas = 48.56 g / mole
Relationship between gas's molecular weight and speed of effusion?
Higher is the molecular mass lower is the rate of effusion, when mass increases by 4 times rate decreases to one half (Graham's law of diffusion).
Mass of a mole?
The molar mass of an element is its atomic weight in grams. The molar mass of a molecule or compound is the sum of the subscripts times the molar masses in grams. For example, the molar mass of hydrogen, H, is 1.00794g and the molar mass of oxygen, O, is 15.9994g. The molar mass of water, H2O, is (2 x 1.00794g) + (1 x 15.9994g O) = 18.01528g.
If you have 6.50 molar of chromium which is a molar mass of 52 grams what is the amount in grams of this amount of chromium?
You will have 6,5 times 52 grams = 338 grams
Mass of 3 moles of ammonia?
Molar mass of ammonia = (14.01 + 3.03) (Molar mass of nitrogen + 3 times molar mass of hydrogen, as chemical formula of ammonia is NH3). Molar mass= 17.04 Molar mass x moles = mass 17.04 x 3 = 51.12 Mass of 3 moles of ammonia is 51.12g.
What is 10 folds molar ratio mean?
A 10-fold molar ratio means that there are 10 times as many moles of one substance compared to some other substance.
What is 76 times 2 by estimate?
160 by estimate
What is the molar mass of sulfur molecule?
A sulfur molecule has the formula S8. Multiply the number of sulfur atoms (8) times the atomic weight of sulfur in grams (32.065g). The molar mass of S8 = 256.52g S8.
How do you estimate 3444 times 670 with rounding?
You can calculate 3444 times 670 without rounding or you can estimate it WITH rounding. But you cannot estimate it without rounding.
How many times faster helium diffuses than oxygen at room temperature calculate?
He molar mass = 4 g/molO2 molar mass = 32 g/mol Rate of diffusion is inversely related to the square root of the molar mass. √4 = 2 √32 = 5.7 5.7/2 = 2.8 So, He diffuses about 2.8 times faster than oxygen.
