Verify by calculating that (a) 5 moles of CO2 and 5 moles of H2O do not have the same mass
(a) 5 moles of CO2 and 5 moles of H2O do not have the same mass.
Ans. CO2 has molar mass = 44g mol–1
5 moles of CO2 have molar mass = 44 × 5 = 220 g
H2O has molar mass = 18 g mol–1
5 moles of H2O have mass = 18 × 5 g = 90 g
