Question

The density of aluminum is 2.70 g/cm³. The volume of a solid piece of aluminum is 4.50 cm³. Find its

mass.
12.2 g
7.20 g
0.600 g
1.67 g

Answer 1

A.) 12.2g

Step-by-step explanation:

The relationship between density, volume, and mass is illustrated in the equation
`d=(m)/(v)`, where

d= density

m= mass

v= volume

Rewrite the equation to solve for mass:

m=d*v

For this problem, let

d=2.70
`(g)/(cm^3)`

v=4.50
`cm^3`

So,

`m=(2.70(g)/(cm^3))(4.50cm^3)\\m=12.15g`
