Question 17 of 20 Submit What is the energy of a mole of photons that have a wavelength of 683 nm? (h = 6.626 x 10-34 Jos and c = 3.00 x 108 m/s) 4 5 8 7 +/- 9 0 x 100 Tap here or pull up for additional resources

Answer 1

ANS= 1.8* 10⁵ J [THANK YOU VERY MUCH]

(693nm = 683x10 m or 6.83x10-7m. DATE TITTI S Ihm = 10-9 me I mole = 6.022 x 10 Photon & 15 = too KI Step-1 Given T © Wavelength (a) = 683.nm = 6:23 x 10 mm © C = 3X108 m/s ③ h = 6.626 X 10 -34 JS. o to Calculate the energy of 1 mole photon Slep-2 Energy of one photon on E= h / Step 3 Energy of 1 mole C6:022 X7023photon E = 6.022 X 1023 23 6.022 X10 X 6.626 X10 X 5 X (6 6.83 x 10-7 E = 119.705 x 10-5 6.83 x 10-7 17.526 X 104 E = E= 1.7526x 105 or 1.8 x 105 J in KJ Thank E = 1.8 x 10 kJ / AGETI you very much. And 18x10² kg -
