Question

Aspartame is an artificial sweetener, it

consists of the elements C, H, O and N.
The complete combustion of 0.001 mol of
aspartame gives 162 mg of water. Its per-
cent mass composition is given as: C: 57.1
%, H: 6.1 %, N: 9.5 %.
a) Calculate the percentage by mass of
oxygen.
b) Calculate the number of mole atoms of
H present in 1 molecule of aspartame.
Deduce the number of H atoms present
in 1 molecule of aspartame.
c) Determine the molecular formula of
aspartame.​

Answer 1

Step-by-step explanation:

Aspartame⇒ C14H18N2O5

SO, the number of atoms of H contain in 1 molecule of Aspartame is 18.

1 mole of h = 1g

27.3= Oxygen percentage
