How much energy (in joules) is contained in one mole of photons (electromagnetic quanta) of frequency 5.9E+19 Hz?

Over ninethousand joules

find energy in each photon,
multiply to find total energy in a mol.

You should know the formulas man

He spelled the subject "Chemestry" I doubt he's the brightest tool in the shed.

e = h * f
e = 6.62606896 x 10^-34 J*s  x  5.9 x 10^19 (1/s)
e = 6.62606896 x 5.9 x 10^-15 Joules
e = 39.093806864 x 10^-15 Joules
e = 3.9093806864 x 10^-14 Joules

Now, we just multiply that by 6.02 x 10^23, since that's all a mole is:

3.9093806864 x 10^-14 J x 6.02 x 10^23 =
23.534471732128 x 10^9 Joules =
2.3534471732128 x 10^10 Joules

He can't even spell the subject right don't fucking help him

wait, moles are made out of photons? how do evolutionists explain that?!
