Question

The percentage composition of 'H' in
HCI​

Answer 1

Answer:

Thus, the percent composition of hydrogen and chlorine is 2.74% and 97.26% respectively.

Explanation:

HCl is made up of Hydrogen (H) and Chlorine (Cl)

Molar mass of H = g(Hy d r o g e n )    = 1 g

Molar mass of Cl =g (chlorine)= 35.5 g

Molecular mass of HCl =

 g T= 1 + 35.5 = 36.6 g

Using percent composition formula,

Percent composition of hydrogen is:

% C ( H y d r o g e n )  =  g ( H y d r ogen )  /  g T  × 100

= (1/36.5) × 100

= 2.74%

Percent composition of chlorine is:

% C ( H y d r o g e n )  = 100% - % C ( H y d r o g e n )= 100% - 2.74% = 97.26%

Answer: Thus, the percent composition of hydrogen and chlorine is 2.74% and 97.26% respectively.
