Two gas cylinders have identical volumes and contain gases at identical temperatures and pressures. cylinder a contains hydrogen and cylinder b contains carbon dioxide. assuming ideal-gas behavior, which of the following variables differ for the two gases:
(a) number of gram-moles,
(b) number of molecules,
(c) masses,
(d) specific molar volumes (l/mol),
(e) mass densities (g/l)?
for each of the quantities that differ, which one is bigger and by how much? (assume ideal-gas behavior.)
