Density of ammonia gas at STP in gL-1?
Don't know how to work it out

At STP, gases have a molar volume of 22.414 liters; that is, one mole of any gas
occupies 22.414 liters at STP.
The molecular weight of ammonia (NH3) is 17.03, so 1 mole of ammonia has a
mass of 17.03 grams.
So at STP, 17.03 grams of gaseous ammonia occupy 22.414 liters, so one liter
has a mass of 17.03/22.414, or 0.7598 gram.
So the density of ammonia at STP is 0.7598 gram per liter.Source(s): college chemistry
