Question

1. how many grams of fe are there in 65.2 grams fecl₃?

Explanation:

Step1: Find molar mass of FeCl₃

Molar mass of FeCl₃ = 55.85 + 3×35.45 = 162.2 g/mol

Step2: Calculate moles of FeCl₃

Moles of FeCl₃ = $\frac{65.2}{162.2}$ = 0.402 mol

Step3: Determine moles of Fe

1 mole of FeCl₃ has 1 mole of Fe, so moles of Fe = 0.402 mol

Step4: Calculate mass of Fe

Mass of Fe = 0.402×55.85 = 22.4 g

Answer:

22.4 g
