Question 70

Carbon monoxide burns in oxygen to form carbon dioxide.

2CO+O2→2CO22\text{CO} + \text{O}_2 \rightarrow 2\text{CO}_22CO+O2​→2CO2​

Relative atomic masses (ArA_rAr​): C=12\text{C} = 12C=12, O=16\text{O} = 16O=16

A 14 g sample of carbon monoxide is burned in excess oxygen until all of it has reacted.

Calculate the mass of carbon dioxide produced.
