Number Density

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	\(\large{ ft^3 }\)	\(\large{m^3}\)
