Chemistry  Stoichiometry Involving Solutions Worksheet 
1. 
Calculate the number of mL of 2.00 M HNO_{3}
solution required to react with 216 grams of Ag according to the equation. 

3 Ag(s) + 4 HNO_{3}(aq)
> 3 AgNO_{3}(aq) + NO(g) + 2 H_{2}O(l)

2. 
Calculate in mL the volume of 0.500 M NaOH required
to react with 3.0 grams of acetic acid. The equation is: 

NaOH(aq) + HC_{2}H_{3}O_{2}(aq) > NaC_{2}H_{3}O_{2}(aq)
+ H_{2}O(l)

3. 
Calculate the number of grams of AgCl formed when 0.200
L of 0.200 M AgNO_{3} reacts with an excess of CaCl_{2}.
The equation is: 

2
AgNO_{3}(aq) + CaCl_{2}(aq) > 2 AgCl(s) + Ca(NO_{3})_{2}(aq)

4. 
Calculate the mass of AgCl formed when an excess
of 0.100 M solution of NaCl is added to 0.100 L of 0.200 M AgNO_{3}.

5. 
Calculate: 

a) the mass of BaSO_{4} formed when excess
0.200 M Na_{2}SO_{4} solution is added to 0.500 L of 0.500
M BaCl_{2} solution, and 

b) the minimum volume of the Na_{2}SO_{4}
solution needed to precipitate the Ba^{2+} ions from the BaCl_{2}
solution.

6. 
A sample of impure sodium chloride weighing 1.00 grams
is dissolved in water and completely reacted with silver nitrate solution.
The dried precipitate of AgCl has a mass of 1.48 grams . Calculate the percentage
of NaCl in the original impure sample.

7. 
To neutralize the acid in 10.0 mL of 18.0 M H_{2}SO_{4}
that was accidentally spilled on a laboratory bench top, solid sodium bicarbonate
was used. The container of sodium bicarbonate was known to weigh 155.0 g
before this use and out of curiosity its mass was measured as 144.5 g afterwards.
The reaction that neutralizes sulphuric acid this way is as follows. 

H_{2}SO_{4}
+ 2 NaHCO_{3} > Na_{2}SO_{4} + 2 CO_{2}
+ 2 H_{2}O 

Was sufficient sodium bicarbonate used? Calculate the
limiting reactant and the maximum yield in grams of sodium sulphate.

8. 
Barium nitrate and potassium sulphate solutions react
and form a precipitate. What is the precipitate? How many mL
of 0.40 M Ba(NO_{3})_{2} solution are required to precipitate
completely the sulphate ions in 25 mL of 0.80 M K_{2}SO_{4}
solution?

9. 
What mass of silver chloride can be precipitated from
a silver nitrate solution by 200 mL of a solution of 0.50 M CaCl_{2}?
