Question

Calculate the molarity of a salt solution with a volume of 0.250L that contains 0.70 mol of NaCl. (SHOW WORK)

Answer 1

Answer:

= 0.28M

Explanation:

data:

volume = 0.250 L

           = 0.250dm^3                       ( 1litre = 1dm^3)

moles = 0.70 moles

Solution:

      molarity = $\frac{no. of moles}{volume in dm^3}$

                 = 0.70 / 0.250

    molarity = 0.28 M
