Question

A 45-gram object that has a volume of 9 mL has a density of

Answer 1

Answer:

 The answer is

a. 5g/mL

Explanation:

Given data

mass m= 45g

volume v= 9mL

we know that density=m/v

substituting our given data we have

$density=\frac{45}{9} =5g/mL$

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 $Density= \frac{mass}{volume}$,

where d is density,

M is mass, and

V is volume.

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