1. A) Calculate thespeed that a gas phase oxygen molecule would have if it had thesame energy of an infrared photon (λ = 5000 nm), avisible photon (λ = 500nm), an ultraviolet photon(λ = 100 nm), an X---ray photon (λ = 0.1 nm). Use theRMS speed for a molecule: √(3kT/M).
B) What temperaturewould the oxygen molecule have to be if it had the same energy forthe above photons?
what mass of sucrose should be combined with 501 g of water to make a solution with an osmotic pressure of 8.85 atm at 305 K? (assume density of solution is equal to the density of the solvent).
The nitrogen in a 4-tablet sample that weighed a total of 7.50 g was converted to ammonia by Kjeldahl digestion, followed by distillation into 100.0 mL of 0.1750 M HCl. The analysis was completed by titrating the excess acid with 11.37 mL of 0.108..
