1.	12. The boiling point of benzene is 353.23 K. When1.80 g of a non-volatile solute was dissolved in90 g of benzene, the boiling point is raised to354.11 K. Calculate the molar mass of the solute.(K for benzene is 2.53 K kg mol-').33
Answer» Explanation: FIND the value of m so that the quadratic equation px^2 + (p – 1) x +(p – 1) = 0 has EQUAL roots.
