3.094 moles of Ca(No3)2 are dissolved in 4.55 kg of water in a 0.68 m solution
Explanation:
1 Kg=1 L for pure water at 4 degrees. So assuming the solvent as pure water, the volume of solution is 4.55 Kg.
Molarity of the solution is given as 0.68
From the formula:
C=n/V ( C concentration of solution) and V ( volume of the solution)
n= C*V
= 0.68*4.55
= 3.094
3.904 of solute is dissolved to make 4.55 liters of solution to obtain a 0.68 m solution
