1. The problem statement, all variables and given/known data 1.) A 500ml flask at 27 degrees Celsius contains He,N2 and Ne the total Pressure is 0.76atm, while Phe= 0.18 atm and Pne= 0.28 atm. Determine the no of moles of N2 in Flask. 2.) Determine the density (g/l) of a gas with a molar mass of 16.0 g/mol at a temperature of 80 degrees Celsius and a pressure of 1.5atm. I thank you guys for the help, please do show your work I really appreciate it. 2. Relevant equations 3. The attempt at a solution I can't seem to figure out what I am doing wrong in these questions I keep getting the wrong answer every time I check my answer it appears to be wrong. Can someone please show me how it's done with the solution so I can see where my mistake was?
