What is the ph of a solution with a concentration of 8.2 × 10-2 molar h3o ?

PH = - log [ H₃O⁺]

pH = - log [ 8.2 x 10⁻²] 

pH = 1.086

hope this helps!

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
