How Many Moles In 13.4 G SO2?

SO₂ is the chemical formula for sulfur dioxide. The molar mass of sulfur dioxide can be calculated as;

Molar mass of sulfur dioxide = 32 + 2* 16

Molar mass of sulfur dioxide = 64

The number of moles of a substance in a sample is equal to the mass of the substance in the sample divided by molar mass of the substance.

Moles = mass in sample / molar mass

Moles = 13.4 grams / 64 grams

Moles = 0.209

The number of moles in the sample of 13.4 grams of sulfur are 0.209.
