Commercially available concentrated hydrochloric acid contains 38 % HCl by mass. (i) What is the molarity of the solution if its density is 1.19 "g cm"^(-2) ? <br> (ii) What volume of concentrated HCl is needed to make 1.0 L of 0.2 M HCl solution ? V1=(0.2M)×(1.0L)(12.38M)=0.01615=16.15mL.

Answer 2

$\huge \tt16.15 \: \: ml$
