Question

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

hey density is simply mass/volume of that object

so here density=89.6/10=8.96g/cm^3

if u hv to answer in kg/m^2 simply convert gram to kg and cm^3 to m^3.

Answer 2

mass of the copper=89.6gram

volume of the copper =10cm cube

The density is

$density = \frac{mass}{volume}$

$density = \frac{89.6g}{10cm {}^{3} }$

$density \:o f \: copper = 8.96gram \: per \: cm {}^{ 3}$

The option (b) is correct
