What is the molarity of a solution containing 78.6 g of mgcl2 dissolved in 1.00 l of solution?

 Molarity of the solution is 0.83 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,

n= moles of solute

= volume of solution  in L

Thus the molarity of the solution is 0.83 M

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