how to calculate change in concentration
To calculate the change in concentration, you need to subtract the initial concentration from the final concentration. The formula is:
Change in concentration = Final concentration - Initial concentration
For example, if the initial concentration of a substance is 0.2 M and the final concentration is 0.5 M, the change in concentration would be:
Change in concentration = 0.5 M - 0.2 M
Change in concentration = 0.3 M
To calculate the change in concentration, you need to know the initial concentration and the final concentration of a substance in a solution. The formula to calculate the change in concentration is:
Change in concentration = Final concentration - Initial concentration
Here is a step-by-step guide to calculating the change in concentration:
1. Determine the initial concentration: This is the concentration of the substance at the beginning of the experiment or the initial state of the system.
2. Determine the final concentration: This is the concentration of the substance at the end of the experiment or the final state of the system.
3. Subtract the initial concentration from the final concentration: This will give you the change in concentration.
For example, let's say you have a solution with an initial concentration of 0.1 M and the final concentration is 0.3 M. To calculate the change in concentration, you would use the formula:
Change in concentration = Final concentration - Initial concentration
= 0.3 M - 0.1 M
= 0.2 M
So, in this example, the change in concentration is 0.2 M.
