Question 1

How many millilitres of 0.200 mol L-1 FeCl3 are needed to react with an excess of Na2S to produce 1.38 g of Fe2S3 if the percent yield for the reaction is 65.0%?

3Na2S(aq) + 2FeCl3(aq) → Fe2S3(s) + 6NaCl(aq)

◦ 102 mL
◦ 51.1 mL
◦ 43.1 mL
◦ 25.5 mL

Question 2

If 100. mL of 0.400 mol L-1 Na2SO4 is added to 200. mL of 0.600 mol L-1 NaCl, what is the concentration of Na+ ions in the final solution? Assume that the volumes are additive.
◦ 0.534 mol L-1
◦ 0.667 mol L-1
◦ 1.40 mol L-1
