a student adds 0.5 moles of solute to enough water to form 500 ml of solution what is the concentration of the solution he made

The concentration of solution made by the student is 1 M.

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.

The formula used to calculate molarity:

      .....(1)

Given values:

Moles of solute = 0.5 moles

Volume of solution = 500 mL

Plugging values in equation 1:

Hence, the concentration of solution made by the student is 1 M.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

it is stable as it is in group 0 which have full outer shells of electrons
