Some volume of oxygen has a mass of 6 g calculate the mass of the same volume of sulfur oxide (IV)

1. Let’s calculate the chemical amount of oxygen:

n (O2) = m (O2): M (O2) = 6: 32 = 0.1875 mol,

2.since under the same conditions equal amounts of gases occupy the same volume, the chemical amount of sulfur oxide (IV):

n (SO2) = n (O2) = 0.1875 mol;

3.Calculate the mass of SO2:

m (SO2) = n (SO2) * M (SO2);

M (SO2) = 32 + 2 * 16 = 64 g / mol;

m (SO2) = 0.1875 * 64 = 12 g.

Answer: 12 g.
