Question
Suppose a group of students working as lab partners mixed four liquid chemicals
together. The four chemicals mixed were 4.80 mL of water (0.9971 g/mL and
18.01528 g/mole), 22.2 mL of acetone (0.7845 g/mL and 58.080 g/mole), 28.6 mL of
2-propanol (0.786 g/mL and 60.096 g/mole), and 22.3 mL of acetic acid (1.049 g/mL
and 60.052 g/mole). Calculate the mass percentage of 2-propanol to 2 decimal
places.
