Question

Data: the mass of an object is 19.5 g and the volume of the object is 14.0 mL.

Which choice below shows the correct answer for density?
(Density is mass/volume)

Select one:
a. 1.2
b. 1.3
c. 1.9
d. 1.39
e. 1.1

Answer 1

Answer: -

The density of the object is (d) 1.39 g / mL

Explanation: -

The mass of an object is given as 19.5 g.

The volume of the object is 14.0 mL.

We are given the formula for density.

The given formula is

Density =
`(Mass)/(Volume)`

Plugging in the supplied values we get

Density =
`(19.5 g)/(14.0 mL)`

= 1.39 g/ mL

The answer is correct to 3 significant figures.

Thus the correct option is d.
