Calculate the mass of SO3 gas that forms when 10g of SO2 reacts with oxygen

Answer 1

1. Write the equation and balance it.

2. Convert what you have into moles. moles= grams/molar mass.

3. Using the coefficients in the balanced equation convert moles of what you have to moles of what you want.

4. Now convert moles of what you want to grams. g = moles x molar mass.
