Achemist dissolves an unknown solute into 1000 grams of water and then measures the freezing point to be -2.88 c what can be determined from this data and from known constants for water?

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
