Unformatted text preview: How many grams does one molecule of carbon dioxide weigh? (a carbon mono xide molecule contains one atom of carbon and one atom of oxygen what do you think carbon di oxide is?) 7.3x1023 g is the mass of one CO 2 molecule 3) From Exam 1, Fall 2006 Given that the density of chromium is 7.19g/cm 3 , what is the approximate diameter of a chromium atom? 3 22 23 3 / 10 3 . 8 1 10 . 6 52 1 1 19 . 7 cm atoms x mole atoms x g mole cm g = By inverting you find 1.2x1023 cm 3 /atom, the volume of one atom. Finding the diameter of the cubic volume that the atom occupies, diameter = (1.2x1023 cm 3 ) 1/3 = 2.3x108 cm...
