How many molecules is 15.2l of NO2?
The answer is 5,213.10 ex.23.
Is NO molecular or ionic?
Molecules of NO2 contain covalent bonds
How many moles of no2 are present in 138.08?
Assuming you mean 138.08 grams, you set up a direct proportion between the molar mass of NO2 and your given mass. NO2 comes in at 46g/mol (14+16+16), and your proportion should be 46/1=138.08/x. Solve for x to get approx. 3 moles.
What is the molar mass of nitrogen dioxide nearest gram?
The molar mass of nitrogen dioxide (NO2) is approximately 46 grams per mole.
How many atoms are in the compound NO2?
3
How many grams of nitrogen dioxide must react with water to produce 5.00x10 22 molecules of nitrogen monoxide?
To produce 5.00x10^22 molecules of nitrogen monoxide (NO), you need an equal number of molecules of nitrogen dioxide (NO2). With the balanced chemical equation 2NO2 + H2O → 2NO + 2HNO3, you can calculate the mass of nitrogen dioxide needed using the molar masses of NO2 and NO.
How many moles of molecules are in 25.5g of NO2?
To find the number of moles of NO2 in 25.5g, you need to divide the given mass by the molar mass of NO2. The molar mass of NO2 is 46.01 g/mol. Therefore, 25.5g ÷ 46.01 g/mol = approximately 0.554 moles of NO2.
How many molecules are in 25.0 g NO2?
To find the number of molecules in 25.0 g of NO2, you can start by converting the mass to moles using the molar mass of NO2. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many molecules are in 19.6 g of NO2?
To determine the number of molecules in 19.6 g of NO2, you first need to calculate the number of moles in the sample. Then, you can use Avogadro's number (6.022 x 10^23 molecules per mole) to convert moles to molecules.
How many molecules is 15.2l of NO2?
The answer is 5,213.10 ex.23.
How many moles are in 4.651024 molecules of NO2?
To find the number of moles, divide the number of molecules by Avogadro's number. 4.651024 molecules of NO2 divided by 6.022 x 10^23 molecules/mol equals approximately 7.72 x 10^-24 moles.
4NH3 7O2 4NO2 6H2O how many grams of oxygen are necessary to produce 4.50 moles of NO2?
To determine the grams of oxygen needed to produce 4.50 moles of NO2, use the coefficients in the balanced equation. In this case, 7 moles of O2 are required to produce 4 moles of NO2. Calculate: (4.50 moles of NO2) * (7 moles of O2 / 4 moles of NO2) = 7.88 moles of O2. Finally, convert moles to grams using the molar mass of O2 (32.00 g/mol): 7.88 moles * 32.00 g/mol = 252.16 grams of O2.
How many gas molecules are there in 1 mole of NO2?
There are approximately 6.022 x 10^23 gas molecules in 1 mole of NO2. This number is known as Avogadro's constant.
A gas contains NO2 molecules at 44C What is the average speed of the molecules and the mass of a NO2 molecule is 7 point 64 times 10 to the negative 26 kg?
ABigNumber.
how many moles of NO2 are in 7.4 mol N2O5?
N2O5(g) → 4NO2(g) + O2(g)
Is NO molecular or ionic?
Molecules of NO2 contain covalent bonds
How many atoms are there in 1.3 x 1022 molecules of NO2?
To find the number of atoms in 1.3 x 10^22 molecules of NO2, we need to consider the number of atoms in each molecule. NO2 has 3 atoms (1 nitrogen and 2 oxygen). So, the total number of atoms in 1.3 x 10^22 molecules of NO2 would be 3.9 x 10^22 atoms.
