Answer:
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
