The concentration of water vapor in a sample of air that has a partial pressure of water of 0.91 torr and a total pressure of air of 735 torr is __________ ppm.

Environmental chemistry is the study of chemical processes in the air, water, soil, and living environments. It also studies how human activity affects these environments.  Environmental chemistry is an interdisciplinary science that includes atmospheric, aquatic, and soil chemistry. It involves studying the sources, reactions, transport, effects, and fates of chemical species in these environments.  Environmental chemists monitor the air, water, and soil to understand how chemicals enter the environment and affect human and ecological health.

Environmental chemistry is an interdisciplinary science that includes atmospheric, aquatic, and soil chemistry. It involves studying the sources, reactions, transport, effects, and fates of chemical species in these environments. 
Environmental chemists monitor the air, water, and soil to understand how chemicals enter the environment and affect human and ecological health. They also assess the long-term risks of contaminants in soil and groundwater. 
Some important topics in environmental chemistry include: Air pollution, Water pollution, Acid rain, Global warming and greenhouse effect, Soil pollution.
