Dear chemical forums, this assignment is due in 4 hours and I got 0.75/1 points making me think I got incorrect significant figures but I am pretty sure my answer is correct. I do not understand why I got deducted points. Please help me understand what I did wrong. Thank you in advance for your help.

Ka2 is given to 2 sig figs, isn't it?
