Answer #1

Given starting materials:
Benzoic acid: 12g
60.0mL isoamyl alcohol
Mass of isoamyl alcohol = 0.809g/mL * 60.0mL = 48.54g
% recovery of benzoic acid    = (recovered mass / starting mass)*100  = (0.345g/12g)*100  = 2.88%
% recovery of isoamyl alcohol    = (recovered mass / starting mass)*100 = (0.157g/48.54g)*100 = 0.32%
