#2) Hydrazine (N2H4) is a weak base (Kb = 9.6 x 10-7). A student prepares a solution by adding an unknown mass of hydrazine to a flask of water with a total volume of 2.00 L. The resulting solution had a pH of 9.01. Calculate the mass of hydrazine that was initially dissolved in the flask. Be sure to include an acid-base equilibrium equation and an ICE table.

Solutions

Expert Solution

mass of N2H4 initially dissolved = 7.552 X 10^-3 grams
