<h2><u>Question</u>:-</h2>
A 10cm³ sample of copper has a density of 897g/cm³. What is the mass of the sample ?
<h2><u>Answer</u>:-</h2>
<h3>Given:-</h3>
Density of sample of copper is 897g/cm³.
Volume of sample of copper is 10cm³.
<h3>To Find:-</h3>
The mass of the sample.
<h2>Solution:-</h2>
We know,

So, Mass = 897g/cm³ × 10cm³
Mass = 8970 g
<h3>The mass of the sample is <u>8</u><u>9</u><u>7</u><u>0</u><u> </u><u>g</u>. [Answer]</h3>
It is not an exact representation of the atom, so it is not very useful.
