Question 6

A standby electricity generator uses 240 kg of diesel each day. It operates for 25 days.

The diesel contains 0.0010% sulfur by mass. All the sulfur reacts with oxygen:

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

Relative atomic mass (ArA_rAr​): O = 16 S = 32

Calculate the mass of sulfur dioxide released, in kg.
