What is the theoretical yield for CCl4 reacting with 100.0 grams of Cl2 with excess CS2.

Theoretical yield of CCl₄ = 72.3 g

Explanation:

Given dа ta:

Mass of Cl₂ = 100.0 g

Theoretical yield of CCl₄ = ?

Solution:

Chemical equation:

CS₂ + 3Cl₂ → CCl₄ + S₂Cl₂

Number of moles of Cl₂:

Number of moles = mass/molar mass

Number of moles = 100 g / 71 g/mol

Number of moles = 1.41 mol

Now we will compare the moles of Cl₂ with CCl₄.

Cl₂ : CCl₄

3 : 1

1.41 : 1/3*1.41 = 0.47 mol

Theoretical yield of CCl₄:

Mass = number of moles * molar mass

Mass = 0.47 mol * 153.82 g/mol

Mass = 72.3 g
