question

The vapour pressure of benzene is 53.3kPa53.3 \mathrm{kPa} at 60.6∘C60.6^{\circ} \mathrm{C}, but it fell to 51.5kPa51.5 \mathrm{kPa} when $19.0 \mathrm{~g}$ of an non-volatile organic compound was dissolved in $500 \mathrm{~g}$ of benzene. Calculate the molar mass of the compound.
Plain-text mathematical notation (without MathML)
The vapour pressure of benzene is 53.3kPa at 60.6^(∘)C, but it fell to 51.5kPa when $19.0 \mathrm{~g}$ of an non-volatile organic compound was dissolved in $500 \mathrm{~g}$ of benzene. Calculate the molar mass of the compound.
