The number of moles $= \dfrac{Mass}{Molarmass}$

The number of molecules $= moles \times {N}_{A}$

One mole of any gas occupies $22 . 7L$ at STP.

(A) Moles of ${CH}_{4} = \dfrac{16}{16} = 1$
Molecules $= 6 . 02 \times {10}^{23}$
Electrons $= 10 \times 6 . 02 \times {10}^{23}$
$= 60 . 2 \times {10}^{23}$

(B) Moles of ${H}_{2} = \dfrac{1}{2} = 0 . 5$ mole
Volume at STP $= \dfrac{1}{2} \times 22 . 7 = 11 . 35lit$ .

(C) 1 mole ${N}_{2} = 28gm$

(D) $0 . 5$ mole ${SO}_{2} = \dfrac{1}{2} \times 64 = 32gm$
