what is the mass of an object if its density is 1.36 g/ml and its volume is 28 ml? express your answer to the correct number of significant figures.

a. 20.59 g
b. 21 g
c. 38.1 g
d. 38 g

1 answer

Using the formula for density (density = mass/volume), we can rearrange the formula to solve for mass.

mass = density * volume

mass = 1.36 g/ml * 28 ml

mass = 38.08 g

The correct answer, expressed to the correct number of significant figures, is:

d. 38 g
