Answer: -
6.31 x [tex] 10^{-8} [/tex]
Explanation:-
The question gives us the value of the pH of urine solution as 7.2
We need to find the H+ concentration [H+].
The relation between [H+] and pH is
[H+] = [tex] 10^{-pH} [/tex]
= [tex] 10^{-7.2} [/tex]
= 6.31 x [tex] 10^{-8} [/tex]
6.31 x [tex] 10^{-8} [/tex] is the h+ concentration in a urine sample that has a ph of 7.2
