Molarity of the solution resulting from dissolving 34.9 g of silver nitrate in enough water to give a final volume of 337 ml

Molarity = 0.61 M.

Explanation:

atomic mass of AgNO3 = 108 + 14 + 3×16 = 170 g.

therefore number of moles in 34.9 g of AgNO3 =

molarity = (number of moles of solute)/(volume of solution in Litre)

             = = 0.61 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.
