ANSWER:

•What is 1 g/mL or 1 g/cm3

Topic 3 – 30 Points

QUESTION:

• If the mass is 400 g and the volume is 200 mL, this is the density.

ANSWER:

•D=M/V which is 400g/200mL= 2 g/mL

Topic 3 – 40 Points

QUESTION:

• This is the density of a piece of styrofoam with a mass of 80 g and a volume of 160 cm3

ANSWER:

•D=m/v = 80g/160 cm3 = 0.5 g/cm3
