Question
The equation for the burning of octane is:
\[\ce{2C6H18 + 25O2 -> 16CO2 + 18H2O}\]
If the relative molecular mass of carbon dioxide is 44, what is the mass of carbon dioxide produced by burning two moles of octane?

Solution
1 mole of carbon dioxide has molecular mass = 44
16 moles of carbon dioxide has molecular mass = 44 × 16
= 704 g
