acid, determine the concentration of the hydrochloric acid. b. 0.4201 g of an unknown monoprotic acid was dissolved in 25.00 mL of water and titrated with 0.09995 M NaOH. It was found that 38.76 mL of NaOH was required to reach the equivalence point. Determine the molecular weight of this unknown acid. 3. Attempt the following questions from a "virtual chemistry laboratory". a. Using the Bohr model of the atom, calculate the wavelength, frequency, wavenumber, and energy per mole for photons for the transition ni = 6 to nt = 3 in hydrogen. Pasche %3D b. Based on the Bohr model of the atom, calculate the ionization energy for a single electron in C5+ if the electron begins in the n = 2 level. %3D С. Bar-code scanners at supermarkets emit orange-red laser light with a wavelength of 633 nm.
