It would be mol/dm^3 Formula of concentration: (no. of moles/volume of solution in dm^3) 1 cm^3 = 0.001dm^3 Hope this helped. :)

Molarity and molality is widely used as units for expressing concentration. Concentrations can also be show through mass per univ volume. Another example is by parts such as parts per million and parts per billion. Lastly, it can also be expressed through percent by mass or volume.

Explanation:

We are given the following diagram.

In this diagram we can see how the energy in the reaction changes over time. The energy of the products is greater than the energy of the reactants. That means that the products have won some energy. That represents an endothermic reaction where the reactants absorb energy from the surrounding to form the products.

Answer: D. Endothermic reaction.
