Question

Select the correct answer.
Daniel has a sample of pure copper. Its mass is 89.6 grams (g), and its volume is 10 cubic centimeters (cm3). What’s the density of the sample?
A.
0.11 g/cm3
B.
8.96 g/cm3
C.
11.1 g/cm3
D.
896 g/cm3

Answer 1

Answer:

• D. 896g/cm3

it is because the pure copper mass is 89.6 gram and the volume is 10 cm cube. then we have to doing the division with g/cm3 so the answer will get as 896 g/cm3

Answer 2

The density of the sample is $8.96\ g/cm^3$.

Explanation:

It is given that,

Mass of the copper sample, m = 89.6 gm

Volume of copper, $V=10\ cm^3$

Let d is the density of the sample. It is equal to the mass per unit volume. It is given by :

$d=\dfrac{m}{V}$

$d=\dfrac{89.6\ g}{10\ cm^3}$

$d=8.96\ g/cm^3$

So, the density of the sample is $8.96\ g/cm^3$. Hence, this is the required solution.
