Question

A particular coal contains 2.5% sulfur by mass. When this coal is burned, the sulfur is converted into sulfur dioxide gas. The sulfur dioxide reacts with solid calcium oxide to form solid calcium sulfite.
If the coal is burned in a power plant that uses 2300 tons of coal per day, what mass of calcium oxide is required daily to eliminate the sulfur dioxide?        The answer for this question is 100tons

How many GRAMS of calcium sulfite are produced daily by this power plant? The answer that i got wrong are 2.2 x10^8, 1.53x10^8, 1.6x10^8 and 1.7x10^8 A particular coal contains 2.5% sulfur by mass.

Explanation / Answer

S+ O2 >> SO2
2 SO2 + 2 CaO >> 2CaSO3 + O2

2300 tons = 2086524902 g
mass S = 2.5 x 2086524902 / 100 = 52163122.55 g
Moles S = 52163122.55 g / 32.066 g/mol =1626742.423
= moles CaSO3
Mass CaSO3 = 120.17 g/mol x 1626742.423=195485637 g => 215.486 tons
