erastovalidia [21]

Answer: The energy of a mole of photon associated with this frequency is 49.5\times 10^{-20}J

Explanation:

The energy and frequency are related by :

E=N\times h\times \nu

E = energy of photon

N = number of moles = 1

h = planks constant = 6.6\times 10^{-34}Js

\nu = frequency = 7.5\times 10^{14}Hz

E=1\times 6.6\times 10^{-34}Js\times 7.5\times 10^{14}s^{-1}=49.5\times 10^{-20}J

The energy of a mole of photon associated with this frequency is 49.5\times 10^{-20}J

Calculate the number of oxygen atoms in 2.00 moles of Mn2O7
cluponka [151]
First you should know that there is seven oxygen atoms in one Mn2O7
So 
2.00 moles of Mn2O7 contain 14.00 moles of oxygen...
Then you multiply this no. with Avagadro no....
from formula
Number of moles= no. of particles/avagadro's no..
14.00×6.02×10²³=84.28 atoms of oxygen...
