Answer to Question #198680 in General Chemistry for Brooke Bennett

Question

how would you prepare 2.0L of a 1.0M hci solution from 12.0m stock solution of hci?

Answer 1

The amount of the solute is constant during dilution. So the mole number of HCl is $2×1.0=2 mole.$

The volume of HCl stock is 2/12=0.167 L. So using 0.167 L stock solution and dilute to 2.0 L.
