Question 2
You take 12 g of carbon and 108 g of silver. Which is true? (Ar: C = 12, Ag = 108)
The right answer is the one marked above.
Both contain the same number of atoms. Each is the relative atomic mass of its element in grams, so each holds 6.022 × 1023 atoms.
The 108 g of silver is the greater mass but not the greater count — a silver atom is nine times as heavy, so nine times as much must be weighed to get the same number.
