Question 1

If 200. mL of 0.100 M Na2SO4 is added to 200. mL of 0.150 M NaCl, what is the concentration of Na+ ions in the final solution? Assume that the volumes are additive.
◦ 0.125 M
◦ 0.175 M
◦ 0.05 M
◦ 0.250 M

Question 2

When 50.0 mL of a 1.00 M solution of Fe(NO3)3 are mixed with 50.0 mL of a 1.00 M solution of NaOH, a precipitate forms.  How many moles of precipitate is formed?

Fe(NO3)3(aq) + 3 NaOH(aq) → Fe(OH)3(s) + 3 NaNO3(aq)


◦ 0.33 moles
◦ 1.00 mole
