# Problem: How many grams of iron(III) sulfide form when 62.0 mL of 0.135 M iron(III) chloride reacts with 45.0 mL of 0.285 M calcium sulfide?

###### FREE Expert Solution

For this problem, we have to calculate the mass of iron (III) sulfide formed when 62.0 mL of 0.135 M iron(III) chloride reacts with 45.0 mL of 0.285 M calcium sulfide

Step 1. Write the balanced equation

calcium sulfide + iron (III) chloride → iron (III) sulfide + calcium chloride

CaS + FeCl→ Fe2S3  + CaCl2

Balancing the equation:

3 CaS + 2 FeCl→ Fe2S + 3 CaCl2

Fe2S     2 Fe × 55.85 g/mol Fe = 111.7 g/mol
3 S × 32.06 g/mol S = 96.18 g/mol
Sum
207.88 g/mol
