319355 The vapour pressure of acetone at \({\rm{2}}{{\rm{0}}^{\rm{^\circ }}}{\rm{C}}\) is 185 torr. When 1.2 g of a non-volatile substances was dissolved in 100 g of acetone at \({\rm{2}}{{\rm{0}}^{\rm{^\circ }}}{\rm{C}}\), its vapour pressure was 183 torr. The molar mass \(\left( {{\rm{g}}{\mkern 1mu} {\mkern 1mu} {\rm{mo}}{{\rm{l}}^{{\rm{ - 1}}}}} \right)\) of the substance is:
