What is the mass of 5 moles H2?
The molar mass of H2 is 2 g/mol. To find the mass of 5 moles of H2, you would multiply the molar mass by the number of moles: 2 g/mol * 5 mol = 10 grams.
What is the ratio of the rates of diffusion of hydrogen gas to ethane gas C2H6?
According to Graham's Law of Effusion, the rate of diffusion of a gas is inversely related to the square root of the molar mass. Thus, smaller (lighter) gases diffuse faster than larger, heavier gases. Molar mass of H2 = 2 and molar mass of C2H6 = 30. Sqrt 2 = 1.41 and sqrt 30 = 5.48, so the ratio is 5.48/1.41 = 3.88 or H2 will diffuse almost 4x faster (3.88x) than ethane. The ratio of H2/C2H6 would be the inverse, or 1.41/5.48 = 0.257, meaning that the rate of diffusion of ethane is about 26% that of hydrogen.
How many moles are in 18.0grams of hydrogen gas?
To find the number of moles in 18.0 grams of hydrogen gas, you need to divide the given mass by the molar mass of hydrogen gas. The molar mass of hydrogen gas (H2) is about 2.016 grams/mol. So, 18.0 grams / 2.016 grams/mol ≈ 8.93 moles of hydrogen gas.
What is the molar mass of amonia gas?
The molar mass of ammonia gas (NH3) is approximately 17.03 g/mol.
Hydrogen gas H2 is a promising alternative to fossil fuels How many molecules are present in 1.0 kg of hydrogen gas?
To determine the number of molecules in 1.0 kg of hydrogen gas, we need to convert the mass to moles using the molar mass of hydrogen. The molar mass of hydrogen (H2) is 2.02 g/mol. Then we can use Avogadro's number (6.022 x 10^23) to find the number of molecules in one mole of hydrogen gas.

What is the mass of 1 mole of gas?
39.95 because that is the molar mass of Argon
What is the relationship between the molar mass of a gas and its density?
The relationship between the molar mass of a gas and its density is that as the molar mass of a gas increases, its density also increases. This means that gases with higher molar masses will be denser than gases with lower molar masses.
How many moles of molecules are there in 40.5 g of H2?
To determine the number of moles in 40.5 g of H2, first find the molar mass of H2, which is 2 grams per mole. Next, divide the given mass by the molar mass to find the number of moles. In this case, 40.5 g / 2 g/mol = 20.25 moles of H2.
How many grams of H2 are needed to produce 14.84 g of NH3?
To find the grams of H2 needed, we first calculate the moles of NH3 using its molar mass. Then, we use the balanced chemical equation to determine the mole ratio of H2 to NH3. Finally, we convert moles of H2 to grams using its molar mass.
Is the molar mass of gas dependant on the type of gas?
Yes, the molar mass of a gas is dependent on the type of gas. Each gas has its own unique molar mass based on the atomic or molecular weight of its constituent elements. This value is used to calculate the amount of the gas present in a given volume using the ideal gas law.
How can one determine the molar mass of a gas using the ideal gas law?
To determine the molar mass of a gas using the ideal gas law, you can rearrange the equation to solve for molar mass. The ideal gas law is PV nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. By rearranging the equation to solve for molar mass (M), you get M (mRT)/(PV), where m is the mass of the gas. By measuring the pressure, volume, temperature, and mass of the gas, you can calculate the molar mass using this formula.
What is the mass of 4 moles of CO2?
Hydrogen gas is H2. 1 moles H2 has a molar mass of 2.0158. Thus, 4 moles H2 gas has a mass of2.0158 g/mole x 4 moles = 8.063 g
