Question

An unknown metal has a volume of 20.2 cm³ and a mass of 390 grams. What was the density of this metal?
Group of answer choices

11.3 g/cm³

8.9 g/cm³

7.8 g/cm³

19.3 g/cm³

Answer 1

$\tt \rho=\dfrac{m}{V}$

ρ =  density

m = mass

V = volume

input the value:

$\tt \rho=\dfrac{390}{20.2}=19.3~g/cm^3$
