Question

Cortisone is a molecular substance containing 21 atoms of Carbon per molecule. The weight percentage of Carbon in Cortisone is 69.98%. What is the molecular mass of Cortisone?

Answer 1

Cortisone is a glucocorticoid hormone produced by the adrenal cortex of our body. It is a steroid hormone with molecular formula C21H28O5.

According to the information provided,

                No. of Carbon atoms in one molecule of cortisone= 21
                Percentage weight of Carbon in cortisone = 69.98%

                Let the total molecular weight of cortisone be 'X'.

 % Weight of Carbon =(No. of atoms*Molecular weight) / Total weight of                                                                                                     Cortisone

        (69.98%)/100             =              (21*12)/X
=>         X                           =              ((21*12)*100)/69.98
                                          =               360.10g

Ans:- 360.10g is the average molecular weight of cortisone hormone.

Answer 2

Answer:

According to the Question ,

No. of Carbon atoms in one molecule of cortisone= 21

Percentage weight of Carbon in cortisone = 69.98%

Let the total molecular weight of cortisone be 'X'.

% Weight of Carbon =(No. of atoms*Molecular weight) / Total weight of Cortisone = (69.98%)/100 = (21*12)/X => X = ((21*12)*100)/69.98 = 360.10g

Ans:- 360.10g is the average molecular weight of cortisone hormone
