60.61 g of CuNO3 is dissolved in water to make a 0.400 M solution. What is the volume of the solution in liters?

Sagot :

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.
