Question

define elements and mass of soil compound mass of solution mass of soil​

Answer 1

PRINCIPLES

When a solute is dissolved in a solvent, the mass of the resultant solution is a sum of the mass of the solute and the solvent. This follows the Law of Conservation of Mass:

This differs from the addition of volumes, which is notadditive, since molecules of the solute fit into open spaces between the molecules of the solvent and keeps the total volume lower than expected. Determining percent by mass is a simple and important technique for analyzing a solution's makeup. By definition, a percent is a fractional,unitless value of one component compared to the whole. In this case, the percent by mass can be represented mathematically as:

Although percent by mass is unit-less, this value is sometimes represented with the units (w/w) to convey that the comparison is by mass (weight) only and not by volume. Percent by volumes are indicated as weight per volume (w/v) or volume per volume (v/v).
