What mass of NH4Cl must be added to 250.0 mL of 0.200 M NH3 solution to have a buffer solution at pH=8.90? Assume no volume change. A 15.0-mL sample of a H3PO4 solution is titrated with a 1.00 M NaOH solution. The neutralization reaction is complete when 33.6 mL of NaOH is added. What is the concentration of the H3PO4 solution (in M)?
