what is the volume at standard temperature and pressure for 28.4g of N2H6SO3?
That compound is called ammonium sulfamate and is a white crystalline powder used as a weed killer. Its density is about 1.8 g/cm^3 at STP
You can't use the perfect gas law on powders. The volume will be 28.4/1.8 = 16 cm^3
for more information about the compound
thank you. (:
