Explanation:
a) In 1 mole of methane there are 4 moles of hydrogen atom
Atomic mass of 1 mole of hydrogen atom = 1 g
Mass of hydrogen in 1 mole of methane = 4 × 1 g = 4 g
b) In 1 mole of chloroform there are 1 mole of hydrogen atom
Atomic mass of 1 mole of hydrogen atom = 1 g
Mass of hydrogen in 1 mole of methane = 1× 1 g = 1 g
c) In 1 mole of [tex]C_{12}H_{10}O_{16}[/tex] there are 10 moles of hydrogen atom
Atomic mass of 1 mole of hydrogen atom = 1 g
Mass of hydrogen in 1 mole of [tex]C_{12}H_{10}O_{16}[/tex] = 10 × 1 g = 10 g
d)In 1 mole of [tex]CH_3CH_2CH_2CH_2CH_3[/tex] there are 12 moles of hydrogen atom.
[tex]CH_3CH_2CH_2CH_2CH_3=C_5H_{12}[/tex]
Atomic mass of 1 mole of hydrogen atom = 1 g
Mass of hydrogen in 1 mole of [tex]CH_3CH_2CH_2CH_2CH_3[/tex] = 12 × 1 g = 12 g
