Question

3) A solution contains 61.3 moles of KC103 in 0.25 L of solution. What is the

molarity of this solution?

Answer 1

The molarity of the solution is 245, 2M.

Step-by-step explanation:

We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case KCl03) in 1000ml of solution (1 liter):

0,25 L solution----- 61,3 moles of KCl03

1 L solution----x= (1 L solution x 61,3 moles of KCl03)/0,25 L solution

x=245, 2 moles of KCl03 --> The molarity of the solution is 245, 2M
