**How to calculate moles of gas?_ Knowing the weight of the**

8/06/2009 · a sample of nitrogen gas kept in a container of volume 2.3L and at a temperauture of 32 degrees Celsius exerts a pressure of 4.7 atm. calculate the number of moles of gas present.... Avogadro's number tells you how many particles there are per mole (there are 6.022 23 particles in a mole), so multiplying this number by the number of moles will give you the number of particles. In this case, multiplying by Avogadro's number will give you the number of dihydrogen gas molecules.

**calculate moles of N2 gas produced? Yahoo Answers**

8/12/2010 · If you knew the identity (and therefore its molar mass), then simply divide 0.4 g by the molecular weight to determine the number of moles. With the current set of parameters, you could set up an equation with ideal gas law (PV=nRT), but you need to know the volume of the flask.... First, convert o C to K, 25 o C +273 = 298 K, then solve the ideal gas law for moles and plug in the numbers Example (find pressure) 2.39 moles of an ideal gas at 300 K occupy 29.0 L.

**How many moles of gas are in a Pokémon Gastly**

13/09/2018 · Find the number of moles of each gas present in the sample. The number of moles of a gas is the mass of that gas divided by its molar mass, which we said was the sum of the atomic weights of each atom in the compound. For how to get a sim out of a note 5 Answer: The reaction shows us for every mole of N 2 consumed, 3 moles of H 2 is also consumed. We need 3 moles of hydrogen gas for every mole of nitrogen gas.
