S + O2 --> SO2

3.20 kg = 3200 grams. Convert to mols. mols = grams/molar mass.

Use the coefficients in the balanced equation to convert mols S to mols SO2

Now use PV = nRT, substitute mols for n, substitute the conditions in the problem (P and T) and solve for volume. Don't forget T must be in kelvin.
