What is the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml?

The final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M

Explanation:

According to the dilution law,

where,  

= molarity of stock solution = 2.5 M

= volume of stock solution = 5 ml  

= molarity of diluted solution = ?

= volume of diluted solution = 750 ml

Putting in the values we get:

Therefore the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
