Answer:

3/2 moles

Explanation:

We are given:

Molarity of the solution = 0.450 M

Volume of the Solution = 300 mL OR 0.3 L

Solving for the number of moles:

We know that the formula for molarity:

M = nV          (where n is the number of moles and V is the volume in Liters)

replacing the variables

0.450 = n * (0.3)

n = 0.450 / 0.3

n = 3/2 moles

Therefore, we have 3/2 moles of Na(OH) in the give solution
