1. If 20 moles of HCl was placed in 40 liters of an

NaOH solution, what was the molarity of the NaOH

solution?

A) 0.50 M

B) 2.0M

C) 1.5 M

D) 4.0 M

Respuesta :

Answer:

A) 0.50 M

Explanation:

The computation of the number of molarity of the NaOH is given below:

As we know that

Molarity = Moles ÷ liters

where

Moles is 20

And, the liters is 40

So, the molarity is

= 20 ÷ 40

= 0.50 M

hence, the molarity of the NaOH  solution is 0.50 M

Therefore the A option is correct
