  3. Molarity 100 A solution of sodium hydroxide is prepared from 8.5g solid NaOH dissolved in enough water to give a final volume of 125.0 mL. This is the molarity of that solution. What is 1.7 M? Chem is try

  4. Molarity 200 You would need to dissolve this many grams of solid Cu(SO4)·5H2O in 735.0 mL of dH2O to give a final concentration of 0.385M Cu(SO4) What is 69.86g Cu(SO4)? Chem is try

  5. Molarity 400 The final concentration of 1.3 L of Mg(NO3)2 is 0.22M. This was the original concentration before 500 mL of dH2O were added. What is 0.3575 M Mg(N?O3)2? Chem is try

  6. Molarity 300 22.0mL of a 3.25M stock solution of H3PO4 is diluted with dH2O to a final volume of 100.0mL. This is the molarity of the new solution. What is 0.715 M phosphoric acid? Chem is try

  7. Molarity 500 55.0mL of a 1.225M of KNO3 is diluted to 70.0mL, at which point 2.36g solid KNO3 are added, without a change in volume. This is the new molarity. What is 1.30M KNO3? Chem is try

  9. EM Radiation 200 This is the frequency of an electromagentic wave with λ = 65.0 cm. What is 4.6 x 108 sec -1 Chem is try

  10. EM Radiation 300 If a photon of light carries 6.31 x 10-16 J energy, this is its wavelength. What is 315 pm? Chem is try

  11. EM Radiation 400 A photon of infrared light whose wavelength is 725nm carries this much energy. What is 2.74 x 10-19 J? Chem is try

  12. EM Radiation 500 Looking at the chart below, green plants will absorb light in the blue and red regions of the electromagentic spectrum, but not the green region. It is for this reason that they appear green. These are the values for the energy in joules carried by photons of red and blue light, and this is the more energetic “color” of photon. Next:
