A 122mL sample of a 1.2 M sucrose solution is diluted to 500.0 mL. what is the molarity of the diluted solution

The molarity of the diluted solution is 0.29 M

From the question,

We are to determine the molarity of the diluted solution.

Using the dilution law formula

M₁V₁ = M₂V₂

Where

M₁ is the initial molarity

V₁ is the initial volume

M₂ is the final molarity

and V₂ is the final volume

From the given information,

M₁ = 1.2 M

V₁ = 122 mL

V₂ = 500.0 mL

Putting the parameters into the formula, we get

∴

∴ M₂ = 0.2928 M

M₂ ≅ 0.29 M

Hence, the molarity of the diluted solution is 0.29 M

0.30M

Explanation:

Let solution 1 be the concentrated solution and solution 2 be the diluted solution

(Molarity x Volume)₁ = (Molarity x Volume)₂

(122ml)₁·(1.2M)₁ = (M)₂·(500ml)₂ => M₂ = 122ml ·1.2M / 500ml = 0.2928M ≅ 0.30M

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.
