If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

What are the first two quantum numbers for the electrons located in subshell 4d? what are the first three quantum numbers for the electrons located in subshell 2s? how many electrons can be held in a sublevel l = 3? how many electrons can be held in the energy level n = 4? how many electrons in an atom can share the quantum numbers n = 4 and l = 3?

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
