@X@user.full_name@X@ @GMU: A flexible container was filled with 0.1652 mol of CO at a volume of 19.34 L. How many moles of this gas would there be if the volume increased to 38.15 L? Assume pressure is constant.

@X@user.full_name@X@ @GMU: What is the average speed of Kr molecules (atoms) at 25.00 °C?

@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 highest energy?

@X@user.full_name@X@ @GMU: A flexible container was filled with 0.1125 mol of CO at a volume of 15.17 L. How many moles of this gas would there be if the volume increased to 25.78 L? Assume pressure is constant.
