Question

To create a 0.75M solution of HCI from 3.7 moles of HCI, what should the final volume be?

Answer 1

4.9 L

Step-by-step explanation:

Given data

• Molarity of the HCl solution (M): 0.75 M

• Moles of HCl (solute): 3.7 mol

• Volume of the solution (V): to be found

The molarity is a unit of concentration and it is equal to the moles of solute divided by the liters of solution.

M = moles of solute / liters of solution

liters of solution = moles of solution / M

liters of solution = 3.7 mol / (0.75 mol/L)

liters of solution = 4.9 L
