# Calculating Mass Percents of Lead and Sulfur in Galena

## Understanding Mass Percent

**Mass percent** is a measurement used to describe the composition of a solution in terms of the mass of the solute present in a given mass of the solution. In the context of the given data, the mass percent of lead and sulfur in galena is determined by calculating the ratio of the mass of each element to the total mass of the compound.

## Calculation of Mass Percents

By using the formula **(mass of chemical / mass of total compound) x 100**, we can calculate the mass percent of lead and sulfur in galena. The mass percent of lead is found to be 86.75%, while the mass percent of sulfur is 13.24%. This information provides insight into the composition of galena and the relative abundance of lead and sulfur in the mineral.

## Significance of Mass Percentage

The mass percentage is a crucial parameter in determining the concentration of a solute in a solution. It is commonly used in various fields of chemistry to quantify the amount of a particular element or compound present in a sample. By expressing the composition in terms of mass percent, scientists can accurately analyze the properties and behavior of substances.
