molec/A3 a ppm convertidor - Moléculas por Ångström cúbico a Partes por millón

Conversion derivation

Express both molec/A3 and ppm in the same base unit mol/L (molar), then cancel the shared base unit.

1. 1

   Rewrite molec/A3 in the base unit

   $$1molec/A3=1.66053907\times 10^{-51}mol/L$$
2. 2

   Rewrite ppm in the base unit

   $$1\mathrm{ppm}=0.000001mol/L$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1molec/A3& =\frac{1.66053907\times 10^{-51}\cancel{mol/L}}{0.000001\cancel{mol/L}}\times 1\mathrm{ppm}\\ & =\frac{1.66053907\times 10^{-51}}{0.000001}\mathrm{ppm}\\ & =1.66053907\times 10^{-45}\mathrm{ppm}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{ppm}& =\frac{0.000001\cancel{mol/L}}{1.66053907\times 10^{-51}\cancel{mol/L}}\times 1molec/A3\\ & =\frac{0.000001}{1.66053907\times 10^{-51}}molec/A3\\ & =6.02214076\times 10^{44}molec/A3\end{array}$$
