@X@user.full_name@X@ @GMU: A gas mixture contained 25.08% by weight Ar and 74.92% O2. What was the mole fraction of Ar?

@X@user.full_name@X@ @GMU: A flexible container was filled with CO2 gas at a pressure of 1.493 atm and volume of 18.164 L. What volume would this same gas occupy if the pressure increased to 2.744 atm? Assume temperature is constant.

@X@user.full_name@X@ @GMU: An unknown gas effused through a porous membrane 1.305 times slower than HCN. What is the molecular mass of the unknown gas?

@X@user.full_name@X@ @GMU: A flexible container was filled with CH4 gas at a pressure of 1.988 atm and volume of 16.538 L. What volume would this same gas occupy if the pressure increased to 3.310 atm? Assume temperature is constant.

@X@user.full_name@X@ @GMU: When an electron is initially in a higher energy orbital and transitions to a lower energy orbital the difference in energies of the two orbitals is the energy of the light emitted. Which transition for hydrogen occurs at the smallest wavelength?

@X@user.full_name@X@ @GMU: How much work has been done when the volume of a gas changes from 19.45 L to 14.64 L at a constant pressure of 2.678 atm and temperature?

@X@user.full_name@X@ @GMU: A gas mixture contained 31.92% by weight UF6 and 68.08% N2O4. What was the mole fraction of UF6?
