A certain laser uses a gas mixture made up of 9.00 g HCL, 2.00 g H2, and 165.0 g Ne. What pressure is exerted by the mixture in a 75.0 L tank at 22 degree C? Which gas has the smallest partial pressure?© BrainMass Inc. brainmass.com July 16, 2018, 5:10 am ad1c9bdddf
IDEAL GAS LAW AND PARTIAL PRESSURES
To solve this problem, we need to know the ideal gas law equation:
PV = nRT
Let's plug in the numbers of what we know.
V = 75.0 L
T = 22 C = (22 + 273) = 295 K
R = 0.08206 L-atm/mol-K
What else? We need to know n (moles) in order to calculate P (pressure).
We need to determine the total number of moles of gas.
We have 9.00 g ...
This solution discusses pressure exerted on a gas mixture.
