Finding moles of gas
Webthe amount of substance in mole; Number of particles = 6.02 × 10 23 × mol. Example. Calculate the number of water molecules in 0.5 mol of water. Number of water … WebFor 2 moles of a gas at STP the volume will be 2 moles ⋅ 22.4 L/mol = 44.8 L For 0.5 moles the volume will be 0.5 moles ⋅ 22.4 L/mol = 11.2 L, and so on. The molar volume of a gas is derived from the ideal gas law P V = nRT: P V = nRT → V = nRT P → V n = RT P
