mole per meter cubed (Avogadro constant)

The mole per meter cubed (mol / m ³ ) is the International Unit of amount-of-substance concentration. It is an expression of the number of atom s of a substance per unit volume, and is of interest primarily to chemists and physicists.

One mole is equal to approximately 6.022169 x 10 ²³ , and is also called the Avogadro constant. Thus, 1 mol / m ³ represents approximately 6.022169 x 10 ²³ atoms of a substance in one cubic meter of space.

Sometimes, larger or smaller units are defined by attaching power-of-10 prefix multipliers. For example, a kilomole per meter cubed (1 kmol / m ³ ) is 10 ³ mol / m ³ , or approximately 6.022169 x 10 ²⁶ atoms per cubic meter; a nanomole per meter cubed (1 nmol / m ³ ) is 10 ^-9 mol / m ³ , or approximately 6.022169 x 10 ¹⁴ atoms per cubic meter.
