Question 1

A diesel-powered pump burns fuel during a test. The results are shown in the table.

QuantityValue
Mass of diesel burned1200 kg
Mass of sulfur dioxide formed4.8 kg
Relative atomic mass, ArA_rAr​, of O16
Relative atomic mass, ArA_rAr​, of S32

All the sulfur in the diesel is converted into sulfur dioxide.

S+O2→SO2 \mathrm{S + O_{2} \rightarrow SO_{2}} S+O2​→SO2​

What mass of sulfur was present in every 100 kg of the diesel?
