Question

adenine molecule

nine the structural formula of adenine:

what is the molecular formula of adenine?

c_h_n___

iii. phosphoric acid molecule

examine the structural formula phosphoric acid.
phosphoric acid is much like the phosphate groups
in atp. note: the letter \p\ represents the
element phosphorus.

what is the molecular formula of phosphoric
acid?

h_p o_

Explanation:

Step1: Count atoms in adenine

Count C, H, N atoms in adenine's structural formula. There are 5 C, 5 H, 5 N.

Step2: Count atoms in phosphoric acid

Count H, P, O atoms in phosphoric acid's structural formula. There are 3 H, 1 P, 4 O.

Answer:

Adenine: \(C_5H_5N_5\)
Phosphoric acid: \(H_3PO_4\)
