Hey there! :

Mass = 156 g

Volume = 20.0 mL

Therefore:

Density  = mass / volume

Density = 156 / 20.0

Density = 7.8 g/mL

Answer:

The density is:

D=7.8\frac{g}{mL}

Explanation:

We have the mass and the volume of steel,

m=156g\\V= 20 mL

The density formula is:

D=\frac{m}{V}(1)

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

D=\frac{156g}{20mL}\\ D= 7.8 \frac{g}{mL}
