The balance equation is :
SO2 + CaO → CaSO3

1.
(2100 tons) x (0.025 S) / (32.0655 g S/mol) x (1 mol SO2 / 1 mol S) x 
(1 mol CaO / 1 mol SO2) x (56.0778 g CaO/mol)
= 91.81 tons CaO

2. (2100 tons) x (0.025 S) x (907185 g/ton) / (32.0655 g S/mol) x (1 mol SO2 / 1 mol S) x (1 mol CaSO3 / 1 mol SO2) x (120.1422 g CaSO3/mol)
= 1.784 x 10^8 g CaSO3
