How do you calculate the molarity of NaOH?
Molar Concentration Formula
- The molar concentration formula is given by,
- HCl + NaOH → NaCl + H2O. …
- n(HCl) = (35.0 / 1000 dm3) × 0.250 mol dm-3 …
- The mole ratio NaOH : HCl = 1:1. …
- Now we have the equation,
- 25 cm3 = 25 / 1000 dm3 …
- Therefore, the molar concentration of NaOH. …
- Molar concentration of NaOH = 0.350 mol dm-3
