A sample of 4.25 moles of hydrogen at 20.0 deg C occupies a volume of 25.0 L. Under what pressure is this sample in atmospheres?

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
