Question

Which of the following contains the least number of hydrogen atoms?


​

Answer 1

The least number of atoms is expressed in the sample of argon gas.

Answer 2

"Polyunsaturated fats contains the least number of Hydrogen Atoms"

Explanation:

The number of hydrogen atoms :

For every mole, one gram of hydrogen there are $6.02*10^{23}$ hydrogen atoms (in scientific notation).

The hydrogen atoms(H) present in Hydrochloric acid (HCL) molecule.It is colourless inorganic chemical and pungent smell.

Hydrogen has a 1.01 atomic mass units.

In hydrogen atoms, unsaturated fats have at least one double bond.The double bond has used up one place a hydrogen atoms could connected to chain. It is also not connected (saturated) to all possible hydrogen atoms.

So, Polyunsaturated fats contains the least number of hydrogen atoms.
