Molar mass SF6 = 146.06 g/mol
p = 723 / 760 = 0.951 atm
T = 31 + 273 = 304 K
d = M p / RT = 146.06 x 0.951 / 0.0821 x 304 = 5.57 g/L
M = d x RT/ p
T = 14 + 273 = 287 K
p = 825 / 760 = 1.09 atm
M = 7.535 x 0.0821 x 287 / 1.09 = 162.89 g/mol
Hope this helps :)
Calculate the density of sulfur hexafluoride gas at 703 torr and 23°C.
density is mass/volume so how do i get those from what i am given?
