Question

What is the molarity of a solution that contains 0.00372 moles hydrochloric acid in 2.39 x 10^2 liters of solution

Answer 1

We know that the equation for molarity is as follows:

Molarity = # mol/L

So, we can then plug in the variables:

Molarity = 0.00372 mol/239 L **(I simplified 2.39 x 10^2 L to just 239 L)**

Molarity = 0.00001556 or 1.56 x 10^-5
