Answer:
The answer is Avogadro's Law.
Explanation:
Avogardo's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." The derivation of Avogadro's law follows directly from the ideal gas law is:
where ;
V is the volume of the gas;
n is the amount of substance of the gas (measured in moles);
k is a constant for a given temperature and pressure
P is pressure of the environment
T is temperature of the environment
Answer:
The energy of one photon is 2.21x10⁻²⁴ J. Multiplied by 10²⁵ is 22.10 J.
Explanation:
The energy (E) of a photon is:
Where:
h: is the Planck's constant = 6.62x10⁻³⁴ J.s
λ: is the wavelength of the radiation = 8.97 cm
c: is the speed of light = 3.00x10⁸ m/s
Hence, the energy of one photon is 2.21x10⁻²⁴ J.
Now, if we multiply the answer by 10²⁵ we have:
