Chemistry

A chemist titrates 80.0mL of a 0.6050M trimethylamine CH33Nsolution with 0.2965M HNO3 solution at 25°C . Calculate the pH atequivalence. The pKb of trimethylamine is 4.19 . Round your answerto 2 decimal places. Note for advanced students: you may assume thetotal volume of the solution equals the initial volume plus thevolume of HNO3 solution added.
