Calculate fraction of cyanide existing as the anion; pH, etc

100. For HCN in water, Ka = 2.0E-10. Calculate the fraction of cyanide that exists as the anion rather than in the molecular form at pH values of 4, 7, and 10 (provide answers in that order).

Please only answer if you're 100% sure you're right. My computer program is very picky and likes to tell me the answers are wrong! Thanks :)
