A 1 L flask is filled with 1.40 g of argon at 25 degrees celcius. A sample of ethane vapor is added to the same flask until the total pressure is 1.00 atm.
Whatis the total pressure of Argon in the flask ?
What is the partial pressure of ethane in the flask?
Use PV = nRT to calculate the pressure of Ar in the flask at the beginning.
Then total pressure = partial pressure Ar + partial pressure ethane.
Please, can you give the answer???
i want to double check
the partial pressure of Argon is .888 atm
2.Ptotal = Par + Pethane
