Question details

Estimate the volume, к of one sodium atom ukusing its metallic radius of 186 u Express your answer with the appropriate units. View Available Hints) V- 2.70x10 Piis Submit Previous Ans Correct If you were as big as the Empire State Building, a socium atom would be slightly smaller than a grain of sand. Significant Figures Feedback: Your answers б9 107 p was either rounded differently or used a different number of significant figures than required for this part. Part B Using your answer from Part A, calculate the volume of a mole of .atoms (in ca/φ Assume that the entire volume is occupied by Natoms leaving no gaps or holes between adjacent atoms. Express your answer with the appropriate units View Available Hint(s) molar volume 16.3 revi Correct A volume of 16.3 cis slightly bigger than an iPod shuffle Part C The experimentally measured and generally accepted value for the molar volume of vis abou 23Which of the following best explains why the value calculated in Part B is significantly smaller than the measured values? View Available Hint(s) The molar volume calculated does not take into account that the electron clouds of neighboring sodium atoms repel each other. The metallic radius used in the calculation was based on a smaoverlap between the electron orbitals of neighboring atoms The metallic radius for sodium does not take into account that sodium commonly loses one electron and exists as The molar volume calculated does not take into account that the shape of the sodium atoms affects packing space behween atoms. The metallic radius reported is not very accurate since electron clouds are mostly empty space and have no specific volume
