Question

Calculate the molarity of the following solution. (0.34 mol of LiNO3 in 6.42 L of solution)

Answer 1

Step 1

Molarity can be defined as follows:

$Molarity\text{ \lparen M or mol/L\rparen = }\frac{Number\text{ of moles of LiNO3}}{Volume\text{ of solution \lparen L\rparen}}$

---------------------------

Step 2

Information provided:

0.34 moles LiNO3

Volume = 6.42 L

---------------------------

Step 3

Procedure:

From step1,

Molarity = 0.34 moles/6.42 L

Molarity = 0.053 M

Answer: Molarity = 0.053 M
