Answer:
According to mole concept,
Number of moles (n)= Given mass of Cu(NO3)2/Molar mass of Cu(NO3)2
= 3.13/187.56
= 0.01668 moles
Molarity (M) = Number of moles of solute (n) / Volume of solution in Liters (V)
Volume of solution in Liters (V) = Number of moles of solute (n) / Molarity (M)
= 0.01668/0.75
= 0.02224 L
= 22.24 mL
Thus, volume of the solution is 22.24 mL.
