Calculate the volume in liters of a 0.104 m potassium permanganate solution that contains 375. mmol of potassium permanganate . be sure your answer has the correct number of significant digits. answer should be in l

3.605 L

Explanation:

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity

V = volume of solution in liter ,

n = moles of solute ,

From the question,

M = 0.104 M

n = 375 mmol ,

Since,

1 mmol = 10⁻³ mol

n = 375 * 10⁻³ mol

V = ?

Now, to calculate the volume of  potassium permanganate solution can be calculated by using the above relation -

M = n / V  

Putting the corresponding values ,

0.104 M = 375 * 10⁻³ mol / V

Rearranging the above equation ,

V = 375 * 10⁻³ mol /  0.104 M

V = 3.605 L

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.
