ppb in molec/ų Umrechner - Teile pro Milliarde in Moleküle pro Kubik-Ångström

Conversion derivation

Express both ppb and molec/ų in the same base unit mol/L (molar), then cancel the shared base unit.

1. 1

   Rewrite ppb in the base unit

   $$1\mathrm{ppb}=1\times 10^{-9}mol/L$$
2. 2

   Rewrite molec/ų in the base unit

   $$1molec/{\mathring{\mathrm{A}}}^3=1.66053907\times 10^{-51}mol/L$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ppb}& =\frac{1\times 10^{-9}\cancel{mol/L}}{1.66053907\times 10^{-51}\cancel{mol/L}}\times 1molec/{\mathring{\mathrm{A}}}^3\\ & =\frac{1\times 10^{-9}}{1.66053907\times 10^{-51}}molec/{\mathring{\mathrm{A}}}^3\\ & =6.02214076\times 10^{41}molec/{\mathring{\mathrm{A}}}^3\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1molec/{\mathring{\mathrm{A}}}^3& =\frac{1.66053907\times 10^{-51}\cancel{mol/L}}{1\times 10^{-9}\cancel{mol/L}}\times 1\mathrm{ppb}\\ & =\frac{1.66053907\times 10^{-51}}{1\times 10^{-9}}\mathrm{ppb}\\ & =1.66053907\times 10^{-42}\mathrm{ppb}\end{array}$$
