Answer is: molecular formula of retinol is C ₂₀H₃₀O.

n (C) = 83,84 g : 12 g/mol.

n (C) = 6,99 mol.

n (H) = 10,58 : 1,008 g/mol.

n (H) = 10,5 mol.

n (O) = 5,58 g : 16 g/mol.

n (O) = 0,348 mol.

n (C) : n (H) : n (O) = 6,99 mol : 10,5 mol : 0,348 mol / : 0,348.

n (C) : n (H) : n (O) = 20 mol : 30,1 mol : 1.
