How can i solve this i think i have to know the concentration of the acid H2CO3 but cannot figure it?

calculate the equillibrium constant ka1 for H2CO3 in an aqueous solution with 0,15 M NaCl and a tempreature of 20 celcius when the solution is saturated with CO2 with a partial pressure of 15 kpa and has a pH = 4,36?

Answer 1

Equillibrium constant=4.3×10 ^{-7}
