A chemist prepares a solution of copper(II) sulfate \( \left(\mathrm{CuSO}_{4}\right) \) by measuring out \( 74 . \mathrm{g} \) of copper(II) sulfate into a 500 . mL volumetric flask and filling the flask to the mark with water.
Calculate the concentration in \( \mathrm{mol} / \mathrm{L} \) of the chemist's copper(II) sulfate solution. Be sure your answer has the correct number of significant digits.
\( \square \) \( \mathrm{mol} / \mathrm{L} \) \( \square \) 10
