Question

A power company burns approximately 475 tons of coal per day to produce electricity. if the sulphur content of the coal is 1.2% by weight, how many tons so2 are dumped into the atmosphere each day?

Answer 1

Firstly we need to find the weight of sulphur which is being burnt:   474 x 0.013 = 6.162   Now we need to change this into moles:   6.162/32.1 = 0.192 moles   This is the amount of moles of sulphur but we need to find the amount of SO2. The equation for the formation of SO2 is:   S + O2 -> SO2   Therefore we know that the amount of moles of SO2 is also 0.192 as it is a 1:1 ratio.  So all we need to do now is convert out of moles:   64.1 x 0.192 = 12.3
