means for storage of solar energy. Photovoltaic panels are used to generate electricity, which then is used to separate water into oxygen and hydrogen. In one demonstration project, 275 mL of H2(g) was collected over water at 25°C. The pressure in the collection chamber was 765 torr. At 25°C, water has a vapor pressure of 24 torr. How much hydrogen was collected?
