21. Cаlculаte the number оf аtоms in 10.0 mL оf Hg at room temperature if the density of Hg is 13.6 g/mL. 22. Calculate the mass (in amu) of Carbon-13 using the periodic table and following information: Mass of Carbon-12: 12.000000 amu Natural abundance of Carbon-12: 98.93 Natural abundance of Carbon-13: 1.07 23. What is the wavelength of an electron in meters traveling at 4.11 × 106 m/s? (Use the resting electron mass from the physical constants table.) 24. Suppose the velocity of an electron in an atom is known to have an accuracy (that is, uncertainty) of 1.00 × 103 m/s. What is the electron’s minimum uncertainty in position in meters? (Use the resting electron mass from the physical constants table.) Upload a file or image of your scratch paper when you have completed the exam. Ensure your paper is clearly labeled with the question and answer. You will not be given credit if the question or answer is unclear. Answers must include units.
