Q 1220680511.     Calculate the molecular weight of the solid substance, if the vapour pressure of pure benzene at a certain temperature is `640 mm` Hg. And a non-volatile, non-electrolyte solid weighing `2.175 g` is added to `39.0 g` of benzene. The vapour pressure of the solution is `600 mm` Hg.
Use formula: `p = p_0x_1`
