The acidity level, pH, of a liquid is given by the formula:
where h+ is the concentration of hydrogen ions in the water, measured in moles per liter.
Elijah decides to have a pool party for his birthday party. Before the party, the pool had a pH level of 4.8. After everyone went swimming, they measured the pool, and it had a concentration of h+ ions of .00000042 moles per liter.
