molec/cm3 in ppb Umrechner - Moleküle pro Kubikzentimeter in Teile pro Milliarde

Conversion derivation

Express both molec/cm3 and ppb in the same base unit mol/L (molar), then cancel the shared base unit.

1. 1

   Rewrite molec/cm3 in the base unit

   $$1molec/cm3=1.66053907\times 10^{-27}mol/L$$
2. 2

   Rewrite ppb in the base unit

   $$1\mathrm{ppb}=1\times 10^{-9}mol/L$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1molec/cm3& =\frac{1.66053907\times 10^{-27}\cancel{mol/L}}{1\times 10^{-9}\cancel{mol/L}}\times 1\mathrm{ppb}\\ & =\frac{1.66053907\times 10^{-27}}{1\times 10^{-9}}\mathrm{ppb}\\ & =1.66053907\times 10^{-18}\mathrm{ppb}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{ppb}& =\frac{1\times 10^{-9}\cancel{mol/L}}{1.66053907\times 10^{-27}\cancel{mol/L}}\times 1molec/cm3\\ & =\frac{1\times 10^{-9}}{1.66053907\times 10^{-27}}molec/cm3\\ & =6.02214076\times 10^{17}molec/cm3\end{array}$$
