A student is calculating the molarity of a solution that has 43.54 g of aluminum nitrate dissolved in water to make 4.0 L of water. How many significant figures should the molarity be expressed in? A. one
B. two
C. three
D. Four
Pls give me real answers and not scam links :)

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.
