Methane burns completely in oxygen.
CH4+2O2→CO2+2H2O\text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}CH4+2O2→CO2+2H2O
Relative atomic masses (ArA_rAr): H=1\text{H} = 1H=1, C=12\text{C} = 12C=12, O=16\text{O} = 16O=16
A Bunsen burner burns 24 g of methane.
Calculate the mass of water formed.
