Molarity is defined as the number of moles dissolved in 1 L of solution.
The molarity of KCl has been given as 4.0 M
This means that in 1 L of KCl solution, there are 4 moles dissolved.
We have been asked to find the volume of the solution if there are 8.0 moles of solute.
If 4 moles are in - 1 L of solution
Then 8 moles of solute are in - 1/4 x 8 = 2 L solution
Volume of KCl solution is 2 L.

Answer:
The main purpose for converting numbers into scientific notation is to make calculations with surpisingly large or small numbers less complicated. Since zeros are not used to place the decimal point, all of the digits in a number in scientific notation are meaningful and easier to read. Hope this helps!
