What is the volume of 0.23kg of pure water

The volume of pure water is

Explanation:

To calculate density of a substance, we use the equation:

We are given:

Density of pure water =

Mass of pure water = 0.23kg = 230 g     (Conversion factor: 1 kg = 1000 g)

Putting values in above equation, we get:

Hence, the volume of pure water is

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.
