@X@user.full_name@X@ @GMU: How much work has been done when the volume of a gas changes from 12.47 L to 18.88 L at a constant pressure of 2.138 atm and temperature?

@X@user.full_name@X@ @GMU: What is the shortest wavelength in the Paschen series (nf = 3)? Remember the Rydberg constant is 1.097×10-2 nm-1

@X@user.full_name@X@ @GMU: An unknown gas effused through a porous membrane 1.088 times faster than O2. What is the molecular mass of the unknown gas?

@X@user.full_name@X@ @GMU: What is the arrangement of charge clouds (electron pairs) around the central atom in IF5?

@X@user.full_name@X@ @GMU: What is the molecular shape of XeF4 ?

@X@user.full_name@X@ @GMU: A flexible container was filled with NO2 gas at a pressure of 1.961 atm and volume of 17.475 L. What volume would this same gas occupy if the pressure increased to 4.413 atm? Assume temperature is constant.

@X@user.full_name@X@ @GMU: A flexible container was filled with 0.1195 mol of CH4 at a volume of 10.25 L. How many moles of this gas would there be if the volume decreased to 4.31 L? Assume pressure is constant.

@X@user.full_name@X@ @GMU: A flexible container was filled with N2O4 gas at a pressure of 1.762 atm and volume of 11.645 L. What volume would this same gas occupy if the pressure increased to 3.088 atm? Assume temperature is constant.
