Question no. 2

Calculate the percentage of composition of hydrogen in acetic acid

Solution

We know that,

$percentage \: of \: composition \: of \: element \: = \frac{mass \: of \: element}{mass \: of \: compound} \times 100$

Molecular formula of acetic acid(ethanoic acid) is CH3COOH

MW = 12 + 3 + 12 + 32+ 1

MW = 60

Molecular weight of hydrogen in acetic acid = 4

Percentage of hydrogen =

$\frac{4}{60} \times 100$

= 6.66 %

In the same way,

Percentage of composition of nitrogen in ammonium carbonate

=

$\frac{28}{96} \times 100$

= 29.16 %
