(b) the molar Cl− concentration of the solution.
(c) the mass in grams of NiCl2 contained in each liter of this solution.
Homework Answers
We have been given the following information:
Density of 
Weight by weight 
Molar mass of 
a) Molarity of 
Therefore, the analytical molar concentration of 
is 
b) In 
, 
ions are present. So, to obtain the molar concentration of 
, the molar concentration of 
should be multiplied by 2.
Therefore, the molar concentration of 
in 
is 
c) The mass of 
in 1 L of the solution can be calculated as
Mass of 
Therefore, the mass of 
in grams is
