Mr(NO2) = Mr = 2Ar(O) + Ar(N) = 2 * 16 + 1 * 14 = 46
D(H2) = Mr / Mr(H2) = 46 / 2 = 23
Mr(SO3) = Mr = 3Ar(O) + Ar(S) = 3 * 16 + 1 * 32 = 80
D(H2) = Mr / Mr(H2) = 80 / 2 = 40
Mr(H2S) = Mr = Ar(S) + 2Ar(H) = 1 * 32 + 2 * 1 = 34
D(H2) = Mr / Mr(H2) = 34 / 2 = 17
Mr(CO2) = Mr = 2Ar(O) + Ar(C) = 2 * 16 + 1 * 12 = 44
D(H2) = Mr / Mr(H2) = 44 / 2 = 22
