An aqueous solution of 2% non-volatile exerts a pressure of 1.004 Bar at the normal boiling point of the solvent. What is the molar mass of the solute ? |

Answer» <P> SOLUTION :`(P_(A)^(0) - P_(A))/(P_(A)^(0)) = (w_(B) XX m_(A))/(m_(B) xx w_(A))``(1.013 - 1.004)/(1.013) = (2 xx 18)/( m_(B) xx 98)` `m_(B) = 41.35` gm/mol |
