Question

A chemist must prepare 600. mL of 160. mM aqueous barium chloride ($BaCl_2$) working solution. She'll do this by pouring out some $0.603 \frac{mol}{L}$ aqueous barium chloride stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the barium chloride stock solution that the chemist should pour out. Round your answer to 3 significant digits.

Name: A chemist must prepare 600. mL of 160. mM aqueous barium chloride (BaCl2) working solution. She'll do this by pouring out some 0.603 (mol)/(L) aqueous barium chloride stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the barium chloride stock solution that the chemist should pour out. Round your answer to 3 significant digits.

Step 1

Given concentration of BaCl2 stock solution = 0.603 M Volume of working solution = 600 mL Concentration of working solution = 160 mM = 0.160 M moles of BaCl2 needed = concentration of working solution * volume of working solution moles of BaCl2 needed = 0.160 M * Show more…
