Question

The mass of a 5 mL sample of ethanol is 15.2 grams, what is the density?

Answer 1

Answer:  3.04 grams per mL

Work Shown:

density = mass/volume

d = (15.2 grams)/(5 mL)

d = (15.2/5) grams per mL

d = 3.04 grams per mL

This is the same as writing 3.04 g/mL

Answer 2

d = m/v
d = 5 mL /15.2 g = 0.33 g/mL
