Determine the mass, in grams, needed to prepare 390cm^3 of a 0.85 mol dm^-3 copper(II) sulfate solution starting with solid CuSO4. 5H2O (Mr = 249.68).

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.

C. control over the business
