95. Because atoms, molecules, and ions are very small, they are counted in units of moles, where 1 mole = 6.022 * 1023 molecules. Concentration of ions in a liquid is measured in units of moles per liter. The measure of the acidity of a liquid is called the pH of the liquid and is given by the formula
pH = - log (H),
where H is the concentration of hydrogen ions in units of moles per liter.
a. Water has a pH value of 7.0. How many hydrogen ions are in one liter of water?
