Insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. a bottle contains 275 ml of insulin at a concentration of 50.0 mg/ml . what is the total mass of insulin in the bottle?

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
