1. what is the mass of a mystery substance that has a density of 20 g/ml and a volume of 3 ml?

60 g
0.15 g
6.6 g
17 g

Explanation:

Step1: Recall density formula

$
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass, and $V$ is volume.

Step2: Rearrange formula for mass

$m =
ho\times V$

Step3: Substitute given values

$m=20\ g/mL\times3\ mL = 60\ g$

Answer:

A. 60 g
