Q12 / 180 · COMEDK 2020 · Chemistry

Gram molecular volume of oxygen at STP is

  • A
    $11200 \mathrm{~cm}^{3}$
  • Correct answer
    B
    $22400 \mathrm{~cm}^{3}$
  • C
    $5600 \mathrm{~cm}^{3}$
  • D
    $3200 \mathrm{~cm}^{3}$

Solution

Gram molecular volume of oxygen at STP is $22400 \mathrm{~cm}^{3}$. i.e, volume of 1 mole of axygen molecule $$ =\frac{22400}{1}=22400 \mathrm{~cm}^{3} . $$

Hence, the correct answer is option: 'B'.
