Calculator inputs
Enter two components. The tool converts everything to moles, then computes normalized coassembly ratios.
Example data table
These values demonstrate mass-based inputs. Use “Load Example” to autofill the form.
| Component | Input type | Inputs | Raw moles | Coassembly ratio |
|---|---|---|---|---|
| A | Mass | 1.50 g, 150 g/mol, 98% purity | 0.0098 | 0.6644 |
| B | Mass | 0.90 g, 180 g/mol, 99% purity | 0.00495 | 0.3356 |
Interpretation: A is enriched relative to B under these inputs.
Formula used
This calculator converts each component into moles, then normalizes by stoichiometric factors.
Conversions to moles
n = (m × p/100) / M
m = mass (g), p = purity (%), M = molar mass (g/mol).
n = C × V × p/100
C = molarity (mol/L), V = volume (L).
Coassembly ratio
n_eff = n / ν
ν is the stoichiometric factor for normalization.
R_A = n_eff,A / (n_eff,A + n_eff,B)
R_A is the coassembly ratio for component A.
