If 0.500 liter of gas X weighs .0750 what is the molecular weight of X? (Volume measured at STP)
THANKYOU

22.4 L at STP is the volume occupied by ONE MOLE of a gas.
what exactly do you do? i have no idea wat to do.
The definition of the molar mass of an ideal gas is that mass of gas that occupies 22.4 L at STP. You know the mass that occupies 0.500 L. So if 0.5 L has a mass of 0.0750 g, then 1 L would weigh what? If that mass occupies 1 L, then how much mass would occupy 22.4 L?
o i get it thankyou
