Chemistry question

[Omegachi]

how do you convert atoms into moles?

how do you convert lightwaves to photons?

I make my lab assitant do it.

can i borrow him for a while?

Hi!

There are 6.022E23 (some say 6.023E23) atoms per mole, so... # of atoms in question / 6.022E23 = number of moles.

Alas, it's been a while since I've peered at the number of photons emitted at a given wavelength - sorry!

Cheers,
Andy

Agh! Just looked it up :

Number of photons emitted = power / photon energy.
Photon energy = h (Planck's constant) * frequency.
Velocity = wavelength * frequency

I believe the velocity should be equal to the speed of light, c, so... wavelength * frequency = speed of light = ~ 3.00E8 m/s.
