Molecular Formula is calculated using following formula,
Molecular Formula = n (Empirical Formula) ----- (1)
Calculating n;
n = Molecular Weight / Empirical Formula Weight --- (2)
Empirical formula weight = (12×3) + (1×7) + (14×1) + (16×1)
Empirical formula weight = (36) + (7) + (14) + (16)
Empirical formula weight = 73
Putting values in Eq. 2,
n = 146 / 73
n = 2
Putting Value of n and Empirical Formula in Eq. 1,
Molecular Formula = 2 × C₃H₇NO
Molecular Formula = C₆H₁₄N₂O₂
Result:
Molecular Formula of Lysine is C₆H₁₄N₂O₂.
