what is the molar mass of a 2L sample of gas that weighs 8 g at a temperature of 15 degree celcius and a pressure of 1.5 atm?
what i did was
22.4L (1atm/1.5atm)(273K/288K) = 15.8L =new volume of that specific set up
D= mass/volume
so the new volume * density = molar mass
and so that is 15.8 * 4 = 63.2 is the molar mass and that's the answer.
Then here is my question.
Why is density = 4?
the solution says D = 8g /2L at 15 celcius and 1.5 atm.
but shouldn't it be 8g / 15.8L?
15.8 L is the volume that I found in that temperature and pressure.
