A gas mixture contains 0.150 mol of oxygen gas,0.116 of nitrogen gas, and 0.211 mol of argon gas in a 0.500 L flask at 298K. what is the partial pressure

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

c) should be the answer.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
