Question

a microwave oven uses electromagnetic radiation with a wavelength of 3.00x10^6 nm. calculate energy (in joules) of 1.65 moles of photons of this radiation.

E = hc/wavelength. Wavelength must be in m and E is in joules for ONE photon. So for 1.65 moles of photons that will be multiplied by (6.022E23 x 1.65).
