Question 1

52.5 mL of a solution were diluted to a volume of 6.25 L and then had a concentration of 3.16 M. What was the molarity of the initial solution?
◦ 3.16(52.5/6.25) M
◦ 3.16(6.25/52.5) M
◦ (3.16)(52.5)(6.25) M
◦ 3.16(52.5/6250) M
◦ (6.25)(3.16)/0.0525 M

Question 2

7.0 g of nitrogen is reacted with 5.0 g of hydrogen to produce ammonia according to the chemical equation shown below. Which one of the following statements is FALSE?

N₂(g) + 3 H₂(g) → 2 NH₃(g)

◦ 3.5 g of hydrogen are left over.
◦ Hydrogen is the excess reactant.
◦ Nitrogen is the limiting reactant.
◦ The theoretical yield of ammonia is 15 g.
