Deter - mine how many moles of vitamin A2 contain the same number of atoms as 1.000 mol vitamin A.

1.041 mol

Explanation:

1.000 mol of vitamin A (C₂₀H₃₀O) has 20 + 30 + 1 = 51 moles of atoms. The moles of atoms in 1.000 mol of vitamin A are:

1.000 mol Vit A * (51 mol Atoms / 1 mol Vit A) = 51.00 mol Atoms

If vitamin A2 has the same number of atoms, it also has the same number of moles of atoms, that is, 51.00 moles of atoms.

1 mol of vitamin A2 (C₂₀H₂₈O) has 20 + 28 + 1 = 49 moles of atoms. The moles of vitamin A2 that contains 51.00 moles of atoms are:

51.00 mol Atoms * (1 mol Vit A2/49 mol Atoms) = 1.041 mol Vit A2
