The molecular formula of cortisol is C₂₁H₃₀O₅
Explanation:
To find the cortisol formula we use the following algorithm:
divide each element percentage by the atomic weight of the element
for carbon 69.9 / 12 = 5.83
for hydrogen 8.34 / 1 = 8.34
for oxygen 22.2 / 16 = 1.41
now the we divide the obtained numbers by the lowest one, which is 1.41
for carbon 5.83/ 1.41 ≈ 4
for hydrogen 8.34 / 1.41 ≈ 6
for oxygen 1.41 / 1.41 = 1
the empirical formula of cortisol is C₄H₆O
the molecular formula of cortisol is (C₄H₆O)ₓ
70x = 362.47
x = 362.47 / 70
x ≈ 5.2
carbon ≈ 5.2 × 4 ≈ 21
hydrogen = 5 × 6 = 30
oxygen = 5 × 1 = 5
The molecular formula of cortisol is C₂₁H₃₀O₅
