Mr[SO2] = Ar[O] * 2 + Ar[S] = 16 * 2 + 32 = 64
ω (O) = 32 : 64 * 100 = 50 %
ω (S) = 32 : 64 * 100 = 50 %
Mr[SiH4] = Ar[H] * 4 + Ar[Si] = 1 * 4 + 28 = 32
ω (H) = 4 : 32 * 100 = 13 %
ω (Si) = 28 : 32 * 100 = 87 %
Mr[CrO3] = Ar[Cr] + Ar[O] * 3 = 52 + 16 * 3 = 100
ω (Cr) = 52 : 100 * 100 = 52 %
ω (O) = 48 : 100 * 100 = 48 %
