How much sulfuric acid can be produced from 100 tons of coal if the coal is 2% sulfur by m?

2% of 100 tons is 20 tons of sulfur to be turned into acid. Sulfuric acid has a molecular weight of 98 and sulfur's atomic weight is 32. So, the ratio of sulfur to sulfuric acid is 98/32, which is 3.06, this is called the gravimetric factor. Multiply this times your 20 tons and you get 61.25 tons of acid.
