Textbook Question

Chapter 1, Problem 129E

Calculate the mass in grams of one mole of each of the following (the mass of a single item is given in parentheses): electrons (9.10938 x 10-²⁸g), protons (1.67262 x 10-²⁴g), neutrons (1.67493 x 10-²⁴g), atoms of carbon-12 (1.992646 x 10-²³g), and doughnuts (74 g). Compare the mass of one mole of carbon-12 atoms to the sum of the masses of the particles that it contains. If the doughnut mentioned in this question were made entirely of carbon, how many atoms would it contain?
