In order to determine the rate of photosynthesis (the conversion by plants of carbon dioxide and
water into glucose and oxygen), the oxygen gas emitted by an aquatic plant is collected over water
at a temperature of 293 K and a total pressure of 755.6 mmHg. Over a specific time-period, a
total of 1.56 L of gas is collected. The partial pressure of water at 293 K is 17.55 mmHg. What
mass of oxygen gas (in grams) forms?
