Answer:

2.07 M

Step-by-step explanation:

Given,

Previous Volume,
v_(1)= 345 ml ; Previous molarity,
s_(1)= 1.5 M

Current Volume,
V= 250 ml

Molar mass of NaCl, M = (23+35.5)=58.5 g

Now,

mass of NaCl present in the solution, w =
(v_(1)s_(1)M)/(1000)

= 30.27375 g

Now,

Changed Molarity,
s_(2)=
(w1000)/(VM)

= 2.07 M
