a
Eq. of \(\mathrm{Ag}=\) Eq. of \(\mathrm{O}_2\)

Let \(\mathrm{x}\) gm silver displaced,

\(\frac{\mathrm{x} \times 1}{108}=\frac{5.6}{22.7} \times 4\)

(Molar volume of gas at STP \(=22.7\) lit)

\(\mathrm{x}=106.57 \mathrm{gm}\)

Ans. \(107\)

OR,

as per old STP data, molar volume \(=22.4\) lit

\(\frac{\mathrm{x} \times 1}{108}=\frac{5.6}{22.4} \times 4, \mathrm{x}=108 \mathrm{gm} \text {. }\)

Ans. \(108\)
