A)Molecular formula of ibuprofen is

B)Molecular formula of Cadaverine is

C)Molecular formula of Epinephrine is

Explanation:

Percentage of an element in a compound:

A) Ibuprofen, a headache remedy, contains 75.69% C, 8.80% H, and 15.51% O by mass.

Molar mass of ibuprofen = 206 g/mol.

Let the molecular formula of ibuprofen be =

Number of carbon atoms in 1 molecule of ibuprofen ;

Number of hydrogen atoms in 1 molecule of ibuprofen ;

Number of oxygen atoms in 1 molecule of ibuprofen ;

Molecular formula of ibuprofen :

=

B)  Cadaverine contains 58.55% C, 13.81% H, and 27.40% N by mass

Molar mass of Cadaverine = 102.2 g/mol.

Let the molecular formula of Cadaverine be =

Number of carbon atoms in 1 molecule of Cadaverine ;

Number of hydrogen atoms in 1 molecule of Cadaverine ;

Number of nitrogen atoms in 1 molecule of Cadaverine ;

Molecular formula of Cadaverine :

=

C) Epinephrine  contains 59.0% C, 7.1% H, 26.2% O, and 7.7% N by mass

Molar mass of Epinephrine  = 180 g/mol.

Let the molecular formula of Epinephrine  be =

Number of carbon atoms in 1 molecule of Epinephrine  ;

Number of hydrogen atoms in 1 molecule of Epinephrine  ;

Number of oxygen atoms in 1 molecule of Epinephrine  ;

Number of nitrogen atoms in 1 molecule of Epinephrine  ;

Molecular formula of Epinephrine  :

=

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

um i think it might be a car?
