# Number Density

on . Posted in Classical Mechanics

Number density, abbreviated as n, a dimensionless number, is the concentration of particles per unit volume.

## Number Density formula

$$\large{ n = \frac {N}{V} }$$
Symbol English Metric
$$\large{ n }$$ = number density   $$\large{ dimensionless }$$
$$\large{ N }$$ = total number of moles of substance $$\large{ dimensionless }$$
$$\large{ V }$$ = volume of substance $$\large{ ft^3 }$$ $$\large{m^3}$$
