c
\(74.75\%\) of chlorine means \(74.75\,g\) chlorine is present in \(100\,g\) of metal chloride.

Weight of metal \(= 100\,g - 74.75\,g\)

                          \(= 25.25\,g\)

Equivalent weight

\( = \frac{{weight\,of\,metal}}{{weight\,of\,chlorine\,}} \times 35.5\)

\( = \frac{{25.25}}{{74.75}} \times 35.5 = 12\)

Valency of metal

\( = \frac{{2 \times V.D.}}{{Equivalent\,wt.of\,metal + 35.5}}\)

\( = \frac{{2 \times 94.8}}{{12 + 35.5}} = 4\)

\(\therefore \) Formula of compound \(= MCl_4\)
