Asked by Rashid

A mixture of 1.39 g H2 and 1.60 g He is placed in a 1.00-L container at 27°C. Calculate the partial pressure of each gas and the total pressure.

PH2 = ? atm
PHe = ? atm
Ptotal = ? atm

Please put answer so i can compare to my answer

My calculator is on the blink so I'm out of commission for another week or so until I can get a new one.
Use PV = nRT and solve for pH2. Use again to solve for pHe. Then add the two to find total P.
n for H2 = g H2/molar mass H2.
n for He = grams/molar mass.
