Classify each of these statements as always true, AT; sometimes true, ST; or never true, NT
The density of a gas at STP is its mass divided by molar volume.
Two grams of H2 gas and 32 g of O2 gas at STP have the same number of particles.
One mole of a diatomic gas occupies 22.4 L.
To convert a volume of 3.20 L of hydrogen gas to the number of moles, you would use the conversion factor 22.4 L /1 mol of h2
The density of a gas at STP can be used to calculate the molar mass
