Question

X g of nitrobenzene on nitration gave 4.2 g of m-dinitrobenzene. X =  g. (nearest integer)

[Given: molar mass (in g mol⁻¹) C: 12, H: 1, O: 16, N: 14]

Canvas Classes · Accepted Answer

Step 1: Stoichiometric Calculation for Nitration
Reaction: .
- Molar mass of -dinitrobenzene () = .
- Molar mass of nitrobenzene () = .

Step 2: Finding Required Mass
- Moles of dinitrobenzene obtained = .
- Theoretically, 1 mole of nitrobenzene gives 1 mole of dinitrobenzene.
- Required mass of nitrobenzene = .
The nearest integer is 3.
