If 0.020 mol of LiOH are dissolved to make 4.5L of solution, what is the molarity?
PLEASE WRITE WITH STEPS

Answer 1

Answer:

0.0044 M or mol/L

Explanation:

We have to know that molarity is moles of a certain thing/litres of solution.

So the info we are given is we have 0.020 mol of LiOH and the litres of solution is 4.5L, hence we just plug it into the

Molarity forumla= moles of a certain thing/litres of solution.

Molarity (M)= 0.020/4.5 = 0.0044 M or mol/L
