An industrial furnace burns a batch of heavy fuel oil. Information about the fuel and its combustion is shown in the table.

QuantityValue
Mass of sulfur dioxide formed7.2 tonnes
Sulfur content of the fuel oil0.60% by mass
Relative atomic mass, ArA_rAr​, of O16
Relative atomic mass, ArA_rAr​, of S32

All the sulfur in the fuel oil is converted into sulfur dioxide.
