Question

Transcribed Image Text:A bioengineer preparing cells for cloning bathes a small
piece of rat epithelial tissue in a TRIS buffer (pKb36.01,
formula is (HOCH2)3CNH2). The buffer is made by dissolving
36.762 g of TRIS in enough of 0.104 M HCI to make 1.32 L
of solution. What is the pH of the buffer? Record your
answer with 2 decimals.
