should the sum of the dosing amounts of a compound into different groups match with total concentration of that compound?

The answer to your question can be both yes and no, depending on the context.

1. If the compound is being distributed into different groups without any loss or addition in the process, then yes, the sum of the dosing amounts should match the total concentration of the compound. This is based on the principle of conservation of mass, which states that the total amount of mass in a closed system remains constant, no matter how substances within the system are rearranged.

2. However, if there are other factors at play, such as the compound reacting with other substances, being metabolized, or being lost during the distribution process, then the sum of the dosing amounts may not match the total concentration of the compound.

3. Additionally, if the compound is being distributed into different groups at different times, then the total concentration of the compound may change over time due to factors such as degradation or evaporation.

4. Finally, the method of measurement can also affect whether the sum of the dosing amounts matches the total concentration. If the measurements are not accurate or precise, then there may be discrepancies between the calculated and actual amounts.

So, in conclusion, whether the sum of the dosing amounts of a compound into different groups matches with the total concentration of that compound depends on various factors, including the nature of the compound, the distribution process, and the method of measurement.
