HI is strong acid, so:
[H+] = [HI]
[H+] = 6 × 10^-3 M
pH = -log[H+]
pH = -log(6 × 10^-3) = 2,22

Hello! Hope this helps!
One important measure of the rate at which a radioactive substance decays is called half-life, or t1/2. Half-life is the amount of time needed for one half of a given quantity of a substance to decay. Half-lives as short as 10–6 second and as long as 109 years are common.
