Question

1) Complete the following table for NH₃ (17.03 g/mol) solution:

Density of Solution (g/ml)	Molarity (mol/L)	Molality (mol/ kg solv.)	%wt	ppm
a)  0.996
b)  0.936

2) Treatment of a 1.000g sample of a mixture of soluble chlorides with an excess of AgNO₃ resulted in the formation of 2.592g of AgCl (143.32g/mol).

a) What is the weight percent of Cl^-(35.453g/mol) in the sample?

b) If this sample contains only NaCl (58.443g/mol) and MgCl₂ (95.211g/mol), calculate the weight percent of NaCl and MgCl₂ in the sample.

3) A combustion analysis of 0.1801g sample of an organic compound known to contain just C, H, and O gave 0.03603g H₂O, and the CO₂ produced was collected in a solution of barium hydroxide. After reaction was complete, 0.7894g BaCO₃ (197.34g/mol) was formed.

a) Calculate %wt of C, H, and O in the compound .(H: 1.008; C: 12.011; O: 16.000)

b) Find the empirical formula of this compound.
