Solution
Firstly we need to find the weight of sulphur which is being burnt:
475 x 0.012 = 5.7
Now we need to change this into moles:
5.7/32.1 = 0.177 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 0.177 as it is a 1:1 ratio. So all we need to do now is convert out of moles:
