Your lab partner tells you that he has prepared a solution that contains 1.50 moles of NaOH in 1.50 L of aqueous solution, and therefore that the concentration of NaOH is 1.5 M.

a. Is he correct.
b. If not what is the correct concentration?

Answer:

1.00 M.

Step-by-step explanation:

Hello!

In this case, since the appropriate way to compute the molarity is by dividing the moles of solute by the liters of the solution:


M=(n)/(V)

We plug in the given moles and volume to obtain:


M=(1.50mol)/(1.50L)\\\\M=1.00M

So we prove that the result obtained by him was incorrect.

Best regards!
