Addition of 1.0 g of a compound to 10 g of water increases the boiling point by $0.3^{\circ} \mathrm{C}$. The amount of compound needed to prepare a 500 ml or 0.1 M solution is (given : assume negligible dissociation or association of the compound, boiling point constant $\mathrm{K}_{\mathrm{b}}$ of water $=0.513 \mathrm{K} \mathrm{kg} \mathrm{mol}^{-1}$ )
(a)0.855 g
(b)17.1 g
(c)8.55 g
(d)85.5 g
