What happens to the weight of the mixture when original components are replaced with pure sand?

When original components are replaced with pure sand, the key idea to understand is that weight is a measure of the mass of the material present. In this scenario, if the original components are removed and replaced with an equal volume of pure sand, the total weight of the mixture remains the same as long as the weight of the removed components matches the weight of the sand added.

This situation assumes that there are no losses of material during the replacement process, which means the mass of the components that are being taken out is equal to the mass of the sand being added. Therefore, when assessing the overall weight of the mixture after the substitution, there is no net change; it maintains its original weight even though the composition has changed.

This reasoning highlights that if the two weights are equal, the overall weight of the mixture does not change, leading to the conclusion that there is no net difference in weight.
