Question

To make a 6.50M solution, how many moles of solute will be needed if 12.0 liters of solution are required

Answer 1

Answer:

78 moles of the solute

Explanation:

From the question;

• Molarity of the solution is 6.50 M
• Volume of the solution is 12.0 L

We want to determine the number of moles needed

We need to know that;

Molarity = Number of moles ÷ Volume

Therefore;

Number of moles = Molarity × Volume

Hence;

Number of moles = 6.50 M × 12.0 L

                             = 78 moles

Thus, the moles of the solute needed is 78 moles
