Question

A 2.45 g mixture of BaCl2 and Ba(NO3)2 is dissolved in water.  Excess AgNO3 is added and all of the dissolved chloride ion is precipitated. The resulting precipitate weighs 0.845 g. 

Use the following Molar Masses (in g mol−−1) as required:

Ba: 137.3

Cl:  35.45

Ag: 107.9

N: 14.01

O: 16.00

 

What is the mass of Ba(NO3)2 in the original mixture?  Enter a mass accurate to three significant figures.
