1. Chemical Formula:

The chemical formula for benzanilide is C₁₃H₁₁NO.

2. Atomic Weights:

* Carbon (C): 12.011 g/mol

* Hydrogen (H): 1.008 g/mol

* Nitrogen (N): 14.007 g/mol

* Oxygen (O): 15.999 g/mol

3. Calculation:

* (13 x 12.011) + (11 x 1.008) + 14.007 + 15.999 = 197.23 g/mol

Therefore, the molecular weight of benzanilide is 197.23 g/mol.
