1) List known values

Sample: 4.188*10^22 particles

Sample volume: 1 cm^3

Volume: 14.374 cm^3

List unknown values

Particles expected in a volume of 14.374 cm^3

2) Using conversion factor


\text{expectedParticles}=4.188\cdot10^(22)\frac{\text{particles}}{1cm^3}\cdot14.374\operatorname{cm}=\text{ 6.02}\cdot10^(23)\text{particles}

3) Similarities between 4.188*10^22 and 6.020x10^23

Both numbers are written in scientific notation.

Both numbers have the same number of significant figures (four).

Both numbers tell the number of particles in a certain volume.
