Question 2

A chemist reacts 30.0 cm3 of 0.240 mol/dm3 nitric acid with sodium carbonate solution. The sodium carbonate solution has a concentration of 0.180 mol/dm3.

The equation for the reaction is 2HNO3+Na2CO3→2NaNO3+H2O+CO22\text{HNO}_3 + \text{Na}_2\text{CO}_3 \rightarrow 2\text{NaNO}_3 + \text{H}_2\text{O} + \text{CO}_22HNO3​+Na2​CO3​→2NaNO3​+H2​O+CO2​.

What volume of the sodium carbonate solution reacts exactly with the nitric acid?
