Question

You have combined the following: 7.92mL of 1.122M Fe(NO3)3(aq), 5.02mL of 1.849M NaCl(aq), and 7.09mL of water. What is the concentration of chloride ions in the resulting solution? Assume liquid volumes are additive

Answer 1

final volume: you do it.
moles of chloride ions: .0502*1.849

concCl- = moles of chloride ions/volumeinliters.
