A chemistry graduate student is given 500 ml of a 0.90 M hydrocyanic acid (HCN) solution. Hydrocyanic acid is a weak acid with K.-4.9 10 What mass of NaCN should the student dissolve in the HCN solution to turn it into a buffer with pH 8.987 You may assume that the volume of the solution doesn't change when the NaCN is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. box...
