Explanation / Answer

Number of moles of SO3 = 345g / 80.066 g/mol = 4.31 mol

from the balanced equation we can say that

2 mole of SO3 is produced by 2 mole of SO2 so

4.31 mole of SO3 will be produced by

= 4.31 mole of SO3 *(2 mole of SO2 / 2 mole of SO3)

= 4.31 mole of SO2

mass of 1 mole of SO2 = 64.066 g

so the mass of 4.31 mole of SO2 = 276 g

Therefore, the mass of SO2 reacted would be 276 g
