Question

What is the molarity of a solution that contains 4.53 moles of lithium nitrate in 2.85 liters of solution?

0.874 M
0.629 M
3.77 M
1.59 M
2.57 M
1.98 M

Answer 1

Answer: 1,59 M

Explanation: M= Mol/L =4.53mol/2.85 = 1.59

Answer 2

The molarity of a solution that contains 4.53 moles of Lithium nitrate will be:

"1.59".

Molarity of solution

According to the question,

Number of moles of Lithium nitrate = 4.53 moles

Liters of solution = 2.85

We know the formula,

→ Molarity = $\frac{Number \ of \ moles}{Liters \ of \ solution}$

By substituting the values,

                 = $\frac{4.53}{2.85}$

                 = 1.59

Thus the above response is correct.
