The first option is the correct.
Since we know the mass of one atom of Fe is 56 and that of Cl2 atoms is 71 (one atom has 35.5 mass) hence both of them will be consumed

Consider the aldol condensation between dibenzyl ketone and benzil in strong base. Calculate the molar masses of the reactants a
Sati [7]

Answer:

a) 210.3 g/mol

b) 210.2 g/mol

c) 384.5 g/mol

Explanation:

First step we will calculate the molar masses of ; carbon atom, hydrogen atom and  oxygen atom in each .

<u> Molar mass of dibenzyl ketone</u>

Molar mass of dibenzyl ketone = ∑ molar masses of atoms in dibenzyl ketone

= carbon( 15 ) = 15 ( 12.0107 ) + oxygen ( 14 ) = 1 ( 15.999 ) + hydrogen(14) =14(1.00784)

= 210.26926 ≈ 210.3 g/mol

<u>  Molar mass of benzil</u>

Molar mass of Benzil =  ∑ molar masses of atoms in  Benzil

= carbon( 14) = 14(12.0107) + oxygen(2) = 2 ( 15.999) +  hydrogen(10) =10(1.00784)

= 210.2262 ≈ 210.2 g/mol

<u>Molar mass of 2,3,4,5-tetraphenylcyclopentadienone</u>

Molar mass  = ∑ molar masses of atoms

= carbon ( 29) = 29(12.0107) + oxygen (1) = 1( 15.999 ) + hydrogen(20) = 20(1.00784 )

≈ 384.5 g/mol
