 ???         I calculated this problem and I wanna see if it's correct, please let me know!

Ph of a 0.55m solution of HBro is 4.48. What is the value of Ka for HBro?

(0.55)2 x 4.48 = 3.3x10-5                    I'm not shure if it is correct

It should be about 2*10-9. Show your work, not just plugged numbers.
