Calculate the vapour density of a triatomic gasX if it's relative atomic mass is 16

Question

bobpursley · Answer

triatomic? the Mol mass=48grams PV=nRT so vapour density requires a temp, pressure. so lets do it at STP. one mole One mole occupies 22.4 L at STP. density=48/22.4 g/L= 48000mg/22400cm^3=2.14mg/cm^3 =
