Answer:
800 mL
Explanation:
This is a dilution question so we have to use the dilution formula
c1v1 = c2v2
Where c1 is the concentration and v1 is the volume of the concentrated solution
And c2 is concentration and v2 is volume of the diluted solution to be prepared
Substituting the values in the equation
3.50 M x 480.0 mL = 2.10 M x v2
v2 = 800 mL
A volume of 480.0 mL of 3.50 M solution should be diluted upto a volume of 800 mL to make a diluted copper nitrate solution of concentration 2.10 M
