Q21 / 160 · AP EAMCET 2025 (22 MAY SHIFT 2) · Chemistry

1.95 g of non-volatile and non-electrolyte solute dissolved in 100 g of benzene lowered the freezing point of it by 0.64 K. The molar mass of the solute (in g $\left.\mathrm{mol}^{-1}\right) \left(\mathrm{K}_{\mathrm{f}}\left(\mathrm{C}_6 \mathrm{H}_6\right)=5.12 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\right)$
