The following problems ask you to find the concentration in moles
per liter (M or mol/L) or to use the concentration to find how many
moles are present in a given volume of solution.

1) Find the concentration of a Mg(NO

2) Find the amount of AgNO

3) How many moles of CuCl

4) You have a NaCl solution with a concentration of 0.87 mol/L. How many moles are in 10 mL of the solution? How many moles of NaCl are in 500 mL of solution?

As with any other stoichiometry problem: find the number of moles
first!

1) 3CuSO_{4}(aq) + 2Al(s) → 3Cu(s) +
Al_{2}(SO_{4})_{3}(aq)

How many mL of a 0.750 M solution of copper (II) sulfate are needed to react with an excess of aluminum to provide 14 g of copper? (Hint: work backwards)

2) Using the equation in question one, how many mL of a 0.400 mol/L copper (II) sulfate solution are required to completely react with 15 g of aluminum?

How many mL of a 0.750 M solution of copper (II) sulfate are needed to react with an excess of aluminum to provide 14 g of copper? (Hint: work backwards)

2) Using the equation in question one, how many mL of a 0.400 mol/L copper (II) sulfate solution are required to completely react with 15 g of aluminum?

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

Find the volume of 0.350 M NaHCO_{3} solution required to
react with 7.00 g H_{2}SO_{4}.

4) Using the equation in question three, find the concentration of a NaHCO_{3} solution needed to completely react with 3 mol
H_{2}SO_{4}. Assume you will use a volume of 5.00 L.

Find the volume of 0.350 M NaHCO

4) Using the equation in question three, find the concentration of a NaHCO
