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 $754\mathrm{.}5$ mmHg

$.$ Over a specific time$-$period, a total of $1\mathrm{.}92$ L

of gas is collected. The partial pressure of water at $293$ K

is $17\mathrm{.}55$ mmHg

$.$ What mass of oxygen gas $($in grams$)$ forms?
