Homework Help: chemistry

Posted by emily on Wednesday, October 20, 2010 at 3:55pm.

A coal burning plant that burns 4 metric tons of coal containing 2% sulfur (S) requires 1 metric ton of wet limestone (calcium carbonate) to remove 90% of the sulfur. The process prevents most of the sulfur from being emitted as sulfur dioxide to the air by producing calcium sulfate.

2CaCO3 + 2SO2 + O2 -----> 2CaSO4 + 2CO2

How do I calculate the percentage of limestone converted to calcium sulfate?

Please Help
