A household cleaning agent contains a weak base with the formula \( \ce{NaX}\). 1.00 g of this compound was dissolved in water to give 100.0 mL of solution. A 20.0 mL sample of the solution was titrated with 0.100 mol L\(^{-1}\) hydrochloric acid, and required 24.4 mL of the acid for neutralisation.
What is the molar mass of the weak base?
- 82.0 g mol\(^{-1}\)
- 84.0 g mol\(^{-1}\)
- 122 g mol\(^{-1}\)
- 410 g mol\(^{-1}\)
