Question

What is the molarity of a solution made from dissolving 10.0 moles of NaOH into 5.0

liters of solution?
A. 1.0 M
B. 1.5 M
C. 5 M
D. 2 M

Answer 1

Option D

Step-by-step explanation:

Molarity (M) of any solution is equal to the number of moles (n)of solute in it divided by total volume of solution (V)

Mathematically, it can be represented as

`M = (n)/(V)`

Substituting the given values, we get-

`M = (10)/(5) = 2`

Hence, option D is correct
