Which has more atoms, 12.0 mol of C or 12.0 mol of Ca?​
mr_godi [17]

Answer:

they are equal.

Explanation:

1 mol = 6.022 × 10^23 (Avogadro's constant), which is the number of atoms in 1 mol of any element. Doesn't matter what their atomic mass is, although, of course, 1 mol of carbon weighs less than 1 mol of calcium, but its because their mass is different, but the point is, in 1 mol of any element there is 6.03*10^23 atoms

This is like saying, what weighs more, 10 kg of feathers or 10 kg of metal
