A gas has a volume of 28 L, a temperature of 45 degrees C, and an unknown pressure has its volume increased to 34 L and its temperature decreased to 35 degrees C. If I measure the pressure after the change to be 2.01 atm, what was the original pressure of the gas?

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.
