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

Step-by-step explanation:

According to the dilution law,


M_1V_1=M_2V_2

where,


M_1 = molarity of stock
CuSO_4 solution = 2.5 M


V_1 = volume of stock
CuSO_4solution = 5 ml


M_1 = molarity of diluted
CuSO_4 solution = ?


V_1 = volume of diluted
CuSO_4 solution = 750 ml

Putting in the values we get:


2.5* 5=M_2* 750


M_2=0.017

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