# Calculate the Mass of Sulfur in Galena Sample

## Calculation of Mass of Sulfur in Galena Sample

Galena, a mineral of lead, is a compound of the metal with sulfur. In a 2.34-g sample of galena that contains 2.03 g of lead, we need to calculate the mass of sulfur present in the sample.

**To calculate the mass of sulfur in the sample:**

Given that the amount of galena is 2.34g and the mass of lead is 2.03 g, we can find the mass of sulfur by subtracting the mass of lead from the total mass of galena.

Mass of sulfur = Mass of galena - Mass of lead

Mass of sulfur = 2.34 g - 2.03 g

Mass of sulfur = 0.31 g

Therefore, the mass of sulfur in the sample is 0.31 grams.
