What is the molar mass of calcium bromide?

CaBr2 = 40.078 + 79.9 x 2 => 199.878 g/mol

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.
