Solution Summary: The author explains that most living organisms prefer an environment that has constant pH.
The H3O+ concentration for a solution with the given pH.
Introduction:
Most of the living organisms prefer an environment that has constant pH. The pH of a solution is generally measured by a pH meter or pH indicator paper. The pH of a solution is calculated by the formula,
pH=−log[H+]

The U. S. Environmental Protection Agency (EPA) sets
limits on healthful levels of air pollutants. The
maximum level that the EPA considers safe for lead air
pollution is 1.5 μg/m³
Part A
If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung
volume of 5.40 L.)
