Calculate the molarity of a solution prepared by dissolving 15.0 moles of solute in enough solvent to 50.0 liters of solution.

Molarity of a solution = 0.3 mol/liter

Explanation:

Given:

Moles of solute = 15 moles

Amount of solution = 50 liters

Find:

Molarity of a solution

Computation:

Molarity of a solution = Moles of solute / Amount of solution

Molarity of a solution = 15 / 50

Molarity of a solution = 0.3 mol/liter

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

50.23 i believe is correct but don't quote me on that.
