Linked relations

n = c₁V₁

c₁V₁ = c₂V₂

c₂ = n / V₂

The workspace deliberately computes the final concentration by the dilution relation and independently by n/V₂ from the same sampled amount.

Conservation check

Cross-checked c₂

0.25 mol L⁻¹

Residual

0 mol L⁻¹

A zero residual confirms the two registered calculation paths agree for the same explicit solution state.

Explain the workflow

1Sample: n = c₁V₁ = 1 mol L⁻¹ × 0.025 L = 0.025 mol.
2Dilute: the solute amount is conserved while final solution volume changes from 25 mL to 100 mL.
3Concentrate: c₂ = c₁V₁/V₂ = 0.25 mol L⁻¹.
4Cross-check: n/V₂ reproduces 0.25 mol L⁻¹ from the same aliquot amount.

Scientific boundary

This workspace uses amount concentration in mol L⁻¹ and solution volume. It does not infer solute identity, molar mass, density, activity, ionic strength, pH or non-ideal solution behavior.

Dilution assumes the amount of the tracked solute is conserved. Reaction, precipitation, decomposition, evaporation, transfer loss and volume contraction are outside this bounded model.

The final-volume input is total solution volume. Adding 75 mL solvent to 25 mL solution is not universally equivalent to a 100 mL final solution unless the final volume is actually made up to 100 mL.
