A graduated cylinder contains 100.0 mL of water. An irregularly shaped object is placed in
the cylinder, and the water level rises to the
250.0 mL mark. If the object has a mass of
450 g, what is the density?

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.
