Molar mass of methane=12+4×1=16g/mol
Explanation:
Atomic mass of H=1
Atomic mass of O=16
H
2
O=2×H+1×O
Molar mass of water=2×1+16=18g/mol
(ii) Molar mass of carbon dioxide (CO
2
)
Atomic mass of C=12
Atomic mass of O=16
CO
2
=1×C+2×O
Molar mass of CO
2
=12+2×16=44g/mol
(iii) Molar mass of methane (CH
4
)
Atomic mass of C=12
Atomic mass of H=1
CH
4
=1×C+4×H
Molar mass of methane=12+4×1=16g/mol
