ArbitrLikvidat [17]

Answer:

The answer to your question is below

Explanation:

Data

Substance = NaCl

moles of NaCl = 49

volume = 150 ml

Process

Molarity is a unit of concentration that makes a relation of the moles of a substance and the volume.

Molarity = moles / volume (L)

1.- Convert 150 ml to L

                  1000 ml ------------------ 1 L

                     150 ml -----------------  x

                      x = (150 x 1) / 1000

                      x = 0.15 L

2.- Substitution

Molarity = 49 / 0.15

Molarity = 326. 7

I have a doubt if the number of moles is 49 moles or 49μmoles
