How many liters would you need to make a 0.7 M solution if you have 8.30 mol of
Potassium Chloride?

The answer for the following problem is mentioned below.

Explanation:

Given:

molarity of the potassium chloride solution (m) = 0.7 M

no of moles present in the potassium chloride solution (n) = 8.30 moles

To find:

volume of the potassium chloride solution (V)

We know;

m =

Where;

m represents the molarity of potassium chloride solution

n represents the no of moles of potassium chloride solution

V represents the volume of the solution

So;

0.7 =

V = 11.8 litres

Therefore the volume of potassium chloride solution is 11.8 litres.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
