Question

A sample of ammonium chloride contains 0.2 mol of hydrogen atoms. the no. Of moles of chlorine in the sample is

Answer 1

Answer:

The no. of moles of chlorine in the sample is 0.05 moles.

Explanation:

In 1 mole of ammonium chloride there are 4 mole of hydrogen atom.

if Ammonium chloride contains 0.2 moles of hydrogen atom then moles of ammonium chloride will be:

$\frac{1}{4}\times 0.2 mol=0.05 mol$ of ammonium chloride

In 1 mole of ammonium chloride there are 1 mole of chlorine atom.

So, in 0.05 mole of ammonium chloride there will be:

$\frac{1}{1}\times 0.05 mol=0.05 mol$ of chlorine atom.

The no. of moles of chlorine in the sample is 0.05 moles.

Answer 2

Answer:

0.05 moles

Explanation:

Given in the compound, there is 1 mole of Ammonium chloride.

In terms of atoms in the particular compound, there are 4 moles of Hydrogen atoms in the given compound (For finding given no. of atoms or moles of an element in a compound, just put the subscript number of the element into is coefficient i.e. H⁴ (cannot write the subscript form) to 4H where '4' signifies the number of moles of particular element in the compound).

So there are 4 moles of Hydrogen present in 1 mole/atom of ammonium chloride.

Therefore, 1 mole of Hydrogen atom is present in = ¼ moles of ammonium chloride.

Therefore 2 mole of Hydrogen atoms is present in = ¼×0.2 which gives 0.05 atoms of ammonium chloride.

1 mole of Chlorine is present in 0.05 moles of ammonium chloride

Therefore, in 0.05 moles of ammonium chloride will have 0.05 moles of Chlorine.

Hope this helps ^_^
