Sulfur undergoes combustion to form sulfuur dioxide. If 456g of sulfur is burnt calculate the mass of sulfur dioxide produced.

Write and balance the equation.

Convert 456 g S to mols. moles = grams/molar mass
Using the coefficients in the balanced equation, convert moles S to moles SO2.
Now convert moles SO2 to grams. grams = moles x molar mass.
