This can be proven by the fact that to find the molar mass of a compound, you simply add the molar masses of all the atoms within the compound

Hope this helps

Determine the energy associated with an e- in hydrogen at n=1 and also at n=t?
Ede4ka [16]

Answer:

hydrogen atom when it drops from N 5 to N 2?

so, 275 kJ of energy is released when one mole of electrons "falls" from n = 5 to n = 2. E = hc/λ (this energy corresponds to the energy of one photon; the energy calculated in this problem is for one mole of photons so we will change this after we change the units from kJ to J)

Explanation:

please mark me as brainliest thank you
