Calculate the [OCl] of a 7.03×102 M solution of the weak acid HClO (make an approximate calculation assuming that initial concentration is equal to the equilibrium concentration). Round your answer to 3 significant digits.
HClO = OCl + H+

.....HOCl ==> H^+ + OCl^
I...7.2E2....0.....0
C....x.......x.....x
E..7.2E2 x..x......x
Ka = (H^+)(OCl^)/(HClO)
Substitute and solve for x
