A sample of

1.50\,\text{g}

\mathrm{CuSO_4\cdot5H_2O}

(molar mass

249.7\,\text{g\,mol}^{-1}

) is first dissolved in water to produce

40.0\,\text{mL}

of solution. An additional

60.0\,\text{mL}

of water is then added with thorough mixing. Determine the molarity of

\mathrm{CuSO_4}

in the final solution.
