A 45-gram object that has a volume of 9 mL has a density of a. 5 g/mL
b. 54 g/mL
c. 36 g/mL
d. 405 g/mL

Explanation:

Given data

mass m= 45g

volume v= 9mL

we know that density=m/v

substituting our given data we have

What is Density?

The Density of a body can be defined as the ratio of mass to volume,

or

Density, mass of a unit volume of a material substance. The formula for density is ,

where d is density,

M is mass, and

V is volume.

Density is commonly expressed in units of grams per cubic centimetre.
