The wavelength of the photon is 1026 Å
Rydberg unit of energy corresponds to the energy of the photon whose wave number is Rydberg constant.
The value for the rydberg constant is 10 973 731.6 m-1
The formula for the rydberg constant for hydrogen is
1 / λ = Rh (1 / n1^2 - 1 / n2^2)
where Rh is the Rydberg constant
For the transition of an electron in a hydrogen atom from n = 1 to n = 3
1 / λ = Rh (1 / 1^2 - 1 / 3^2)
1 / λ = Rh (0.888)
λ = 1.126 / Rh
λ = 1.126 / 10 973 731.6
= 1.026 * 10^-7
= 1026 Å
Hence, the wavelength of the photon is 1026 Å

1 mole of any substance contains Avogadro's number.
So, 1 mole of O2= 6.023x10^23 molecules
3 mole of O2= 6.023x10^23x3 molecules
= 1.8069x10^24 molecules
Each molecule of Oxygen has 2 atoms.
therefore,
1.8069x10^24 molecules= 1.8069x10^24 x 2 atoms
= 3.6138x10^24 atoms.
Answer:
The energy released from food was once energy from the sun that was captured by plants in the chemical process that forms plant matter (from air and water). Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion.
