A particular coal contains 2.55% sulfur by mass. When the coal is burned, it produces SO2 emissions which combine with rainwater to produce sulfuric acid.

Determine how much sulfuric acid (in metric tons) is produced by the combustion of 1.1 metric ton of this coal. (A metric ton is 1000kg .)

A: ___ metric ton H2SO4

How do you set this up?

Determine the percent of S in sulfuric acid.

Then:

1.1ton/.0255 * 100/percentSinacid =

I tried this & the % of S in sulfuric acid = 32.7%.
However, when I worked 1.1ton/0.0255*11/0.327 I got:13191.82107. The question says to give to 2sig figs. I entered 1.3*10^4, but said that it was incorrect.

Any other suggestions...or did I just enter the numbers incorrectly?
