Question

what is the volume of an object whose density is 10.5 g/ml and has a mass of 123 grams?
1290 ml
11.7 ml
113 ml
0.0854 ml

Explanation:

Step1: Recall density formula

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

Step2: Rearrange formula for volume

$V = \frac{m}{
ho}$

Step3: Substitute given values

$V=\frac{123\ g}{10.5\ g/mL}\approx11.7\ mL$

Answer:

B. 11.7 mL
