Question

a copper wire has a mass of 9.9 grams and a density of 9.0 grams per cubic centimeter. calculate its volume.
write your answer to the tenths place.
____ cubic centimeters

Explanation:

Step1: Recall density formula

Density $
ho = \frac{m}{V}$, rearrange to $V = \frac{m}{
ho}$

Step2: Substitute given values

$m=9.9\ \text{g}$, $
ho=9.0\ \text{g/cm}^3$, so $V = \frac{9.9}{9.0}$

Step3: Compute and round to tenths

$V=1.1\ \text{cubic centimeters}$

Answer:

1.1 cubic centimeters
