🤓 Based on our data, we think this question is relevant for Professor Brush's class at FSU.
A mixture of 10.0 g of Ne and 10.0 g of Ar has a total pressure of 1.6 atm. What is the partial pressure of Ne?
a. 1.1 atm
b. 0.8 atm
c. 0.54 atm
d. 0.40 atm
e. 1.3 atm
We’re being asked to calculate the partial pressure of Ne in a mixture of Ne and Ar.
Recall that the partial pressure of a gas (PGas) in a mixture is given by:
where χGas = mole fraction of the gas and Ptotal = total pressure of the gas mixture.
The mole fraction of the gas is then given by:
