Question

The students measure that the rock has a mass of 20 g and a volume of 40 mL. What is the density of the rocket in g/mL? Round your answer to the nearest tenths place.

Answer 1

Mass$=20g$

Volume $=40ml$

Density$=unknown$

Density$(\rho)=$ $Mass(m) \over Volume(v)$

From the formula;

$\rho$ $=$ $20g\over 40ml$ $=0.50g^{-1}ml^{-1}$

$\therefore$ The density of the rock$=$ $0.50g^{-1}ml^{-1}$ Or $0.50g/ml$
