determine the concentration of all aqueous species in the final solution when 455mL of 2.95 M lithium bromide is mixed with 755mL of 3.45M silver nitrate.

Answer 1

To determine the concentration of each aqueous species you first find the mole of each species in solution. Then calculate the mole concentration by dividing moles by the total volume.

2.95*(455ml/1000)=1.34 Moles of Li and Br.

3.45*(755mL/1000)=2.61moles of Ag and NO₃

755mL+455mL=1210/1000=1.21L

Li:1.34moles/1.21L=1.11M

Br:1.34moles/1.21L=1.11M

Ag :2.61moles/1.21L=2.16M

NO₃: 2.61mole/1.21L=2.16M
