Explanation:
When diluting a fruit juice, it is important to know the final volume so as not to over dilute the solution.
- The fruit juice can become too diluted if we don't know the final volume .
- Concentration refers to the amount of solute dissolved in a solvent.
- To achieve a desired amount of concentration during dilution, the volume of the target must be known.
- This will serve as a guide of the amount of solvent to add in order to take the solution to the desired volume.

The temperature of the gas is 475 ° Celcius which is equal to: 475 +273= 748 °K. The formula for kinetic energy of individual atoms would be
K= 3/2 * kB * T
If kB is 1.38 * 10^-23 J/K and 1 mol is made from 6.02*10^23 molecule, then the kinetic energy of 1 mol CO2 would be:
K= 3/2 * kB * T
K= 3/2 * 1.38 * 10^-23 * 748 * 6.02 *10^23 =9324 J/mol
