Question

1. how many grams of cl2 are there in 1.50 mol fecl3?

Explanation:

Step1: Determine Cl atoms in FeCl₃

In 1 mol FeCl₃, there are 3 mol Cl atoms. So in 1.50 mol FeCl₃, there are 1.50×3 = 4.50 mol Cl atoms.

Step2: Relate Cl atoms to Cl₂

2 mol Cl atoms make 1 mol Cl₂. So 4.50 mol Cl atoms make $\frac{4.50}{2}= 2.25$ mol Cl₂.

Step3: Calculate mass of Cl₂

Molar - mass of Cl₂ is 70.90 g/mol. Mass = moles×molar - mass, so mass of Cl₂ = 2.25 mol×70.90 g/mol = 159.525 g.

Answer:

159.525 g
