A chemist measured the amount of calcium sulfide produced during an experiment. She finds that of calcium sulfide is produced. Calculate the number of moles of calcium sulfide produced.

0.0836 mol

Explanation:

A chemist measured the amount of calcium sulfide produced during an experiment. She finds that 6.03 g of calcium sulfide is produced. Calculate the number of moles of calcium sulfide produced.

Step 1: Given data

Mass of calcium sulfide: 6.03 g

Step 2: Determine the chemical formula of calcium sulfide

Calcium cation has a charge +2 and sulfide anion has a charge -2. Then, the chemical formula of calcium sulfide is CaS

Step 3: Calculate the moles corresponding to 6.03 g of CaS

The molar mass of CaS is 72.14 g/mol. The moles corresponding to 6.03 g of CaS are:

6.03 g × (1 mol/72.14 g) = 0.0836 mol
