Q)

A $1.37\; M$ aqueous solution of citric acid ($H_3C_6 H_5O_7$; Molecular Weight = $192.1 g/mol$) has a density of $1.10 g/cm^{3}.$ What is the molality and mole fraction of the citric acid?

$\begin{array}{1 1} (A) molarity = 1.24 mol/kg, mole fraction = 0.028 \\ (B) molarity = 1.64 mol/kg, mole fraction = 0.029 \\ (C) molarity = 1.34 mol/kg, mole fraction = 0.039 \\ (D) molarity = 1.54 mol/kg, mole fraction = 0.049\end{array}$
