- Does Avogadro's number have units?arrow_forwardExplain why the total E in an Einstein depends on the frequency or wavelength of the light.arrow_forwardIf the dissociation energy of one mole of O2 is 5.17 eV, determine the wavelength that must be used to dissociate it with electromagnetic radiation. Indicate how many Einstein's of this radiation are needed to dissociate 1 liter of O2 at 25°C and 1 atm of pressure.Data: 1 eV = 96485 kJ mol-1; R = 0.082 atm L K-1; c = 2.998x108 m s-1; h = 6.626x10-34 J s; NA = 6.022x 1023 mol-1arrow_forward
- Indicate the number of Einsteins that are equivalent to 550 kJ mol⁻¹ of absorbed energy (wavelength 475 nm).arrow_forwardIndicate the number of einsteins that are equivalent to 550 kJ mol⁻¹ of absorbed energy?arrow_forwardA unit used in photochemistry is the einstein. If 400 kJ mol-1 of energy has been absorbed, how many einsteins is this equivalent to?arrow_forward
