Explanation:
(i) Molar mass of water (H
2
O) =2×atomic mass of hydrogen +atomic mass of oxygen
Molar mass of water=2(1g/mol)+16g/mol=18g/mol
(ii) Molar mas of CO
2
=atomic mass of carbon+2×atomic mass of oxygen
Molar mass of CO
2
=12g/mol+2(16g/mol)=44g/mol
(iii) Molar mass of methane =atomic mass of carbon+4×atomic mass of hydrogen
Molar mass of methane=12g/mol+4(1g/mol)=16g/mol
