Answer:
1.041 mol
Step-by-step 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
