Five identical 1.5 L flasks contain the gases helium, oxygen, carbon dioxide, ethane (C2H6) and sulfur dioxide. They are stored at 2 C and 1 atm.
Which gas has the greatest density (1pt)? What is the density (1pt)? Round your final answer to
3 significant figures

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

58750.08068 is the answer i think

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

yes the answer is total mass in unchanged   : )
