Answer:
0.74°C
Explanation:
The freezing point depression is a colligative property that can be calculated using the following expression.
ΔTf = Kf . b
where,
ΔTf: depression in the melting point
Kf: freezing point depression constant
b: molality
The mass of the solvent (benzene) is:
The moles of solute (naphtalene) are:
The molality of naphtalene is:
ΔTf = Kf . b
ΔTf = (4.90°C/m) . 0.972m = 4.76°C
The melting point of the solution is:
5.50°C - 4.76°C = 0.74°C
Answer:
The electron took two jumps to return to its ground state.
Explanation:
If the electron is in nth state then it first goes to (n-1)th to 2nd state and emits one photon of this energy gap. Then, it goes to ground state and emits another photon of different energy. It can emit types of different photons. Fourth option is incorrect because in that case it emits one photon and absorbs one photon to go back to that state and also both photons are of same energy.
