The molecular mass of carbon dioxide (CO2) is:
38
44
46
42
Molecular weight of (CO2) = At. wt. of carbon + 2 (At. wt of oxygen) = 12 + 2(16) = 44
Calculate the relative molecular mass of carbon dioxide (CO2) .
Calculate the molecular masses of the following:
(a) Hydrogen, H2
(b) Oxygen, O2
(c) Chlorine, Cl2
(d) Ammonia, NH3
(e) Carbon dioxide, CO2
(Atomic masses: H = 1 u, O = 16 u; Cl = 35.5 u; N = 14 u; C = 12 u)
