The length of the molecule is
in scientific notation.
Data;
- Width of molecule = 3*10^-6 cm
- Number of molecules = 225
<h3>Length of the molecule</h3>
This can be calculated as the total length of the 225 molecules added together. To do this, we simply multiply both the numbers of the molecules by the width of the molecule.
This becomes;
