6. The percentage composition of carbon by mole in methane is (2019 Main, 8 April II)
(a) $75 %$
(b) $20 %$
(c) $25 %$
(d) $80 %$
Show Answer
Answer:
Correct Answer: 6. (b)
Solution:
Key Idea The percentage composition of a compound is given by the formula.
$%$ composition $=[$ Composition of a substance in a compound $/$ Total composition total of compound $] \times 100$
In $CH _4$,
mole of carbon $=1$
mole of hydrogen $=4$
$\therefore$ % of carbon by mole in $CH _4=\frac{1}{1+4} \times 100=20 $%
