# What is the standard volume in NTP

## Molar volume

The molar volume V, also known as the molar volumem is defined as volume, the 1n = 6.022140857 (74) × 1023 Ingesting particles of a substance.

The temperature and pressure dependent size is in m3 mol-1 specified.

The specified amount of substance n corresponds to one mole.

The following applies (with V = volume, n = amount of substance, M = molar mass, NA. = Avogadro constant, ρ = density):
