What is the relative oxygen density of sulfur 4?

Given:
SO2

To find:
D O2 (SO2) -?

Decision:
1) M (SO2) = Mr (SO2) = Ar (S) * N (S) + Ar (O) * N (O) = 32 * 1 + 16 * 2 = 64 g / mol;
M (O2) = Mr (O2) = Ar (O) * N (O) = 16 * 2 = 32 g / mol;
2) D O2 (SO2) = M (SO2) / M (O2) = 64/32 = 2.

Answer: The relative density of SO2 is 2.
