The percentage composition of carbon by mole in methane is:

Options

  1. A75 %
  2. B20 %
  3. C80 %
  4. D25 %

Correct answer

B. 20 %

Step-by-step solution

Chemical Formula of Methane is CH 4 . The mole percentage of carbon = m o l e s   o f    c a r b o n    T o t a l    m o l e s   i n   M e t h a n e × 100 = 1 1 + 4 × 100 = 20 %
