Determine the molar mass of (show your work) : FeCl3•6H2O (note, this is all 1 molecule. Its an FeCl3 with a cage of 6H2O’s attached. These molecules are known as hydrates.)

Ca3(PO4)2

To find molar mass, simply add up the masses of each element. Notice the subscripts as well. I rounded to the nearest whole number, except for Cl (35.5)

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.
