Question

2. You have 4 Liters of a 4 M solution. How many moles are present?

Answer 1

Step 1

Data provided:

Concentration of the solution = 4 M (or 4 mol/L)

Volume of the solution = 4 L

----------------------------

Step 2

Molarity = moles of solute/volume of the solution (L) (1)

Molarity = mol/L or M

--------------------------

Step 3

The moles of solute must be cleared from (1):

Moles of solute = molarity x volume of the solution

Moles = 4 mol/L x 4 L = 16 moles

Answer: moles of solute = 16 moles
