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
[tex]density=\frac{45}{9} =5g/mL[/tex]
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 [tex]Density= \frac{mass}{volume}[/tex],
where d is density,
M is mass, and
V is volume.
Density is commonly expressed in units of grams per cubic centimetre.
