A chemist prepares a solution of barium chloride \( \left(\mathrm{BaCl}_{2}\right) \) by measuring out 4.41 g of barium chloride into a \( 350, \mathrm{~mL} \) volumetric flask and filling the flask to the mark with water.
Calculate the concentration in \( \mathrm{mol} / \mathrm{L} \) of the chemist's barium chloride solution. Be sure your answer has the correct number of significant digits.
\( \square \)
\( \mathrm{mol} / \mathrm{L} \) \( \square \) \( \times 10 \)
