how to find the pH of 0.10 M H2SO4 ??

**chemistry**

how to find a pH for 0.10 M HCL? please explain

**chemistry**

A Ca(OH)2 solution has a pH of 8.0. [H3O+] = 1.0 x 10^-8 and [OH-] = 1.0 x 10^-6 Determine [Ca(OH)2].

**Chemistry**

[OH] = 1.5 x 10^-13 , what is the [H3O] ? This is what I did. 1.0 x 10^-14 M / 1.5 x 10^-13 M = 1/15 or.066666 So what is the correct answer? Thank You
