I need help calculating the pH ? :D

Calculate the pH of blood with a H+ concentration of 60 nmol/L. Identify the acid-base disorder of a patient with this pH (RR 7.35-7.45) who has a bicarbonate of 15 mmol/L (RR 22-32) and a PCO2 of 52 mm Hg (RR 35-45).

I just need help with the calculation , I simply suck at it. I can figure out the disorder this patient is suffering from, its acidosis, either metabolic or respiratory, but that isnt the point, I need step-by-step help to calculate pH from using the information given, I know the pH will be below the normal reference range, just dont know how to calculate it.

Thank you

If [H+] =60 nmol/L=60x10^-9 mol/L

pH=-log([H+])
=-log(60x10^-9)
=7.22

to calculate the pH smpily take the negative log of the H+ concentration
