Question 28

Methane reacts completely with oxygen when the mixture is ignited.

$CH4+2O2→CO2+2H2O\text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}$

A reaction vessel contains methane and 500 cm³ of oxygen before ignition. After the reaction, 180 cm³ of oxygen remains. All gas volumes are measured at the same temperature and pressure.

What was the initial volume of methane in the reaction vessel?
