(i) Molar mass of water ( )
Atomic mass of =0
Atomic mass of
=2 X H +1 X O
Molar mass of water = g/mol
(ii) Molar mass of carbon dioxide
Atomic mass of C=12
Atomic mass of O=16
= 1 X C + 2 X O
Molar mass of
= 12 +2 X 16 =44 g/mol
(iii) Molar mass of methane
Atomic mass of C=12
Atomic mass of H=1
= 1 X C + 4 X H
Molar mass of methane g/mol
Atomic mass of =0
Atomic mass of
=2 X H +1 X O
Molar mass of water = g/mol
(ii) Molar mass of carbon dioxide
Atomic mass of C=12
Atomic mass of O=16
= 1 X C + 2 X O
Molar mass of
= 12 +2 X 16 =44 g/mol
(iii) Molar mass of methane
Atomic mass of C=12
Atomic mass of H=1
= 1 X C + 4 X H
Molar mass of methane g/mol
