Question 1 5 points Save Answer What volume (in mL) of a 369% (w/w) HCI solution must be diluted to prepare 1.000 L of a 0.1000 M HCI solution? The density of 36% (ww) HCI solution is 1.18 g/mL. Molar mass of HCl is 36.46 g/mol. Note: Report only the numerical value (with correct sig fig) in your final answer without the unit and subscript. Round the final answer only, not in the middle of the calculation steps.
