Molarity \( (\text{M}) \) of an aqueous solution containing \( x \,\text{g} \) of anhyd. \( \text{CuSO}_4 \) in \( 500 \,\text{mL} \) solution at \( 32\,^{\circ}\text{C} \) is \( 2 \times 10^{-1} \,\text{M} \). Its molality will be ________ \( \times 10^{-3} \) m. (Nearest integer).
[Given density of the solution \( = 1.25 \,\text{g/mL} \)]
