An aqueous solution of magnesium oxalate is prepared by dissolving 4.46 g of magnesium oxalate in 1.51Ã102 g of water. The density of the solution is 1.01 g mL-1.
a) Determine the mass percent of magnesium oxalate in the solution.
b) Determine the mole fraction of magnesium oxalate in the solution.
An aqueous solution of nickel(II) chloride is prepared by dissolving 5.61 g of nickel(II) chloride in 4.53Ã102 g of water. The density of the solution is 1.34 g mL-1.
Determine the molarity (in mol/L) of nickel(II) chloride in the solution.
