How many moles of HCI are needed to prepare 8.0 liters of a 4.0 M solution of HCI? 0.5 mol HCL

32 mol HCI

12 mol HCL

2 mol HCI

32 mol HCI

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,

n = moles of solute

= volume of solution in Liters

Now put all the given values in the formula of molarity, we get

Therefore, the moles of HCI needed to prepare 8.0 liters of a 4.0 M solution of HCI are 32.
