Answer: The amount of N-acetyl-p-toluidine is

Step-by-step explanation:
To calculate the number of moles, we use the equation:

We are given:
Given mass of N-acetyl-p-toluidine = 0.250 g
Molar mass of N-acetyl-p-toluidine = 149.2 g/mol
Putting values in above equation, we get:

Hence, the amount of N-acetyl-p-toluidine is
