Answer

Why divide ? by Na

Answer

Calculation of Photons per mole of wavelength 250 nm

Given:

Energy per molecule, E = 9.6 x 10^16 J

Wavelength, λ = 250 nm = 2.5 x 10^-7 m

Solution:

The energy of a single photon is given by:

E = hc/λ

Where h is Planck's constant and c is the speed of light.

Thus, the number of photons per molecule can be calculated as:

Number of photons = E / hc/λ

Number of photons = (9.6 x 10^16 J) / (6.626 x 10^-34 J s x 2.998 x 10^8 m/s / 2.5 x 10^-7 m)

Number of photons = 3.05 x 10^21 photons

Now, to calculate the number of photons per mole, we need to use Avogadro's number:

Number of photons per mole = (3.05 x 10^21 photons/molecule) x (6.022 x 10^23 molecules/mol)

Number of photons per mole = 1.83 x 10^45 photons/mol

Answer:

The number of photons per mole of wavelength 250 nm is 1.83 x 10^45 photons/mol.

Answer

20×10 power 10 we have to divide by Na as one mole has Na particles

Answer

Using thisE=nhc/λ, put all the values , u get the value of n and then divide it by avagdro no. And that will be ur answer
