Mole fraction is the ratio of the constituent moles to the total constituents. The mole fraction of sodium chloride is 0.0443.
<h3>What is a mole fraction?</h3>
A mole fraction is the proportion of the moles of the component in a total component present.
In 100 gm of solution 13.0 5 means, there is 13.0 gm of sodium chloride present. The mass of water is calculated as,
100 - 13.0 = 87.0 gm
Moles of sodium chloride is calculated as:
Moles of water are calculated as:
Now, moles fraction is calculated by dividing moles of sodium chloride by total moles as,
Therefore, the mole fraction of sodium chloride is 0.0443.

Explanation:
(amylose and amylopectin)
First you need to write out the original equation.
It needs to be balanced, though, so after balancing it should look like this:
The ionic equation would look like this. (Only aqueous solutions can be split up).
The net ionic equation only contains the products that are not aqueous. Therefore, the final net ionic equation should be:
So your answer is C.

Explanation:
Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy. ... Moreover, the current sources or energy such as fuels are non-renewable in nature and are rapidly consumed. That is why we are facing energy crisis.
