0.10 M methylamine (CH3NH2)
kb= 4.38e-4

calc the percent ionization

so i did the ICE table to find that x=6.62e-3 (that was a typo the first time)
and then i divided by .1 and then multiplied by 100. but i got the wrong answer whats did i do wrong?

my answer was 6.62% but that was wrong... -__-

I solved the quadratic and obtained 0.0064 which is appreciably different than 6.62 x 10^-3 so %ion = 6.40 Why don't you solve it by the quadratic and see if you get the same thing?
