The atmospheric pressure at the highest peak in Pa is 0.997atm. What will the temperature of 0.042mol of oxygen gas be if the volume of the storage tank is 1.0L?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

it should be all of them because it asks if you included all of those in your answer

explanation:

i just learnt this recently but i need to look through my notes again
