Q. The mass of $112{cm}^{3}$ of ${CH}_{4}$ gas at STP is
A) 0.16 g
B) 0.8 g
C) 0.08 g
D) 1.6 g
Explanation
(c)
$\because Mass\ of\ 22400\ {cm}^{3}\ of\ {CH}_{4}\ at\ STP = 16\ g\$
$\therefore\ \ \ \ \ \ \ Mass\ of\ 1\ {cm}^{3}of\ {CH}_{4}\ at\ STP = \ \frac{16}{22400}g$
$\therefore Mass\ of\ 112\ {cm}^{3}\ of\ {CH}_{4}\ at\ STP = \frac{16}{22400}\ \times 112$
= 0.08 g
