The PH of the solution of HCl is calculated as below
Ph= - log H^+
calculate the hydrogen ion concentration
by first write the ionic equation for dissociation of HCl
HCl = H^+ + Cl^-
since the mole ratio between HCl to H^+ is 1:1 the concentration of H^+ =0.01 M
Ph is therefore = - log 0.01 = 2
HCl has a PH of 2
