Question:

If you dissolve 25.5 g KBr in enough water to make 1.75 L of solution, what is the molarity of the solution?

Solution:

We need to know the amount of KBr:

N(KBr) (mol) = 25.5 / 119.0 = 0.21

Now we can find the molarity of the solution:

M(KBr) (mol/L) = 0.21 / 1.75 = 0.12

Answer: 0.12
