A solution comprising \( 0.1 \mathrm{~mol} \) of naphthalene and \( 0.6 \mathrm{~mol} \) of benzene is cooled until some solid benzene freezes out. The solution is then decanted off from solid and warmed to \( 353 \mathrm{~K} \), where its vapour pressure is found to be 608 torr. The freezing and normal boiling points of benzene are \( 278.5 \mathrm{~K} \) and \( 353 \mathrm{~K} \) respectively. The amount of benzene that freezes out due to cooling is \( \mathrm{x} \mathrm{g} \). The value of \( 5 \mathrm{x} \) is
