Canvas Classes · Accepted Answer

Strategy:
 For multi-step synthesis, the final molar yield is the product of all intermediate yields. Calculate the moles of each intermediate progressively and then determine the final mass using the molar mass of the product.

Step 1: Track moles through the sequence
Initial:  acetophenone.
1. Step A (60%): 
2. Step B (50%): 
3. Step C (50%): 
4. Step D (100%):

Step 2: Calculate mass of product D
Molecular formula of 2,4,6-tribromoaniline is .
Molar mass .
