Hello!
In an endothermic reaction, The potential energy of the products is greater than the potential energy of the reactants.
Any chemical reaction that absorbs energy is called an Endothermic Reaction. In this reactions, the reactants absorb energy from the surroundings to carry out the reaction. As a result, the products have a higher potential energy than the reactants. Photosynthesis is an example of an Endothermic Reaction, as the plant uses energy from the sun to generate the products.
Have a nice day!
Answer:
5.5 moles of given substance.
Explanation:
The given problem can be solved by using the Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
Solution:
3.311 ×10²⁵ / 6.022 × 10²³ = moles
5.5 moles of given substance.
