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?
