Lysine is used as a topical medicinal skin creme. what is the molecular formula of lysine if the empirical formula is c3h7no, and the approximate molar mass is 146 g/mol

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.

The answer to this question is a

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
