Hi,
here's the problem :
A 60 gal tank contain pure Azote at 36,2 psig and 24,2 °C. We add 908,25 g of freon (CF2Cl2) that evaporate completely. If the temperature of the tank is 8,2 °C :
a) What is the molar fraction of the freon.
I've made some calculation, but it always result...
The molar fraction is the (number of mol for the freon) / (total number of mol). I found the number of mol for the freon = 7,51161 mol.
Now I need the total number of mol. So I need the
(number of mol for the freon) + (number of mol for the azote) / (Molar weight of freon) + (Molar weight of...

I don't know,... they gave me the total weight before and I need the total weight after...I don't know how to find the weight of the gas or the weight of the cylinder...they juste gave me the total.
HI,
Here's the question :
A cylinder is fill with Argon (Ar) at 25 °C and 102,4 kPa with a total weight of 312,50 g. The dimension of the cylinder is 32,4 mm of diameter and 1,2162 m long. We remove Argon with a vacuum pump. What will be the total weight of the cylinder if the inside...
