Homework Help: chemistry

Posted by lynne on Tuesday, July 1, 2008 at 1:29am.

I have been staring at this one for awhile now... I would so appreciate any help on approaching this problem!

A certain sample of coal contains 1.6 percent sulfur by mass. When the coal is burned, the sulfur is converted to sulfur dioxide. To prevent air pollution, this sulfur dioxide is treated with calcium oxide (CaO) to form calcium sulfate (CaSO3.) Calculate the daily mass (in kg) of CaO needed by a power plant that uses 6.60 x 10^6 kg of coal per day.
