Question

Calculate mass and volume of oxygen required at stp to convert 3.2 kg sulphur into so2

Answer 1

s+o2 = so2

to convert 1mole of sulphur to sulphurdioxide,1mole of oxygen is required
I.e 32g of sulphur required 32g of oxygen
therefore,
3.2kg require x kg of oxygen

and x=3.2×32/32
=3.2 kg
