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

= 0.28M

Step-by-step explanation:

data:

volume = 0.250 L

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

moles = 0.70 moles

Solution:

molarity =
`(no. of moles)/(volume in dm^3)`

= 0.70 / 0.250

molarity = 0.28 M
