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 KK and a total pressure of 753.3 mmHg. Over a specific time-period, a total of 1.84 LL of gas is collected. The partial pressure of water at 293 KK is 17.55 mmHg. What mass of oxygen gas (in grams) forms? Express your answer with the appropriate units.
The total pressure consists of the partial pressure of H2OH2O and the partial pressure of O2O2. Recall that if you calculate the number of moles of O2, you should use the partial pressure of O2O2 in the ideal gas law equation. Once you calculate the number of moles of O2O2 convert to mass using its molar mass. |
