Web1 egg mass = 60g and 1 dozen = 12. Therefore, 1 dozen of egg masses = 1 dozen of 60g = 12 of 60g = 12 x 60g = 720g Example 2: Show that 1 mole of 12C is 12g. Recall that, 1 amu = 1.6605 x 10^ (-27) kg and 1 mole = 6.02 x 10^23. 12C = 12 amu Therefore, 1 mole of 12C = 1 mole of 12 amu = 1 mole of 12 x 1.6605 x 10^ (-27) kg WebApr 26, 2024 · How many atoms are there in one ounce of pure gold?
