Question

156 g sample of steel has a volume of 20.0 mL. what is the density of the steel sample

Answer 1

Hey there! :

Mass = 156 g

Volume = 20.0 mL

Therefore:

Density = mass / volume

Density = 156 / 20.0

Density = 7.8 g/mL

Answer 2

The density is:

`D=7.8(g)/(mL)`

Step-by-step explanation:

We have the mass and the volume of steel,

`m=156g\\V= 20 mL`

The density formula is:

`D=(m)/(V)`(1)

We can replace the mass and the volume in the equation (1) to find the density:

`D=(156g)/(20mL)\\ D= 7.8 (g)/(mL)`
