mmol_l_to_mols¶

hgana.utils.mmol_l_to_mols(c, V)¶

Convert the concentration in \(\frac{\text{mmol}}{\text{l}}\) to number of molecules.

The concentration in regard to volume is calculated by

\[c=\frac{N}{N_A\cdot V}\]

with volume \(V\). Assuming that the unit of the concentration is \(\text{mmol}\cdot\text{l}\) and of the volume is \(\text{nm}^3\), the number of molecules is given by

\[N=c\cdot N_A\cdot V =[c]\cdot10^{-27}\,\frac{\text{mol}}{\text{nm}^3}\cdot6.022\cdot10^{23}\,\frac{1}{\text{mol}}\cdot[V]\,\text{nm}^3\]

and thus

\[\boxed{N=6.022\cdot10^{-4}\cdot[c]\cdot[V]}\ .\]

Parameters:	c : float Concentration in \(\frac{\text{mmol}}{\text{l}}\) V : float Surface in \(\text{nm}^3\)
Returns:	N : float Number of molecules
