Question

How many moles of KCl are contained in this solution?

0.486 L of a 2.0 M KCl solution

Answer 1

0.972mol

Step-by-step explanation:

Given parameters:

Volume of Solution of KCl = 0.486L

Molarity = 2.0M

Unknown:

Number of moles of KCl in solution = ?

Solution:

To find the number of moles of KCl in this solution, use the expression below;

Number of moles = molarity x volume

Insert the parameters and solve;

Number of moles = 0.486 x 2 = 0.972mol
