The balanced reaction is:
\[\text{C}_6\text{H}_5\text{NH}_2 + \text{C}_6\text{H}_5\text{N}_2^+\text{Cl}^- \rightarrow \text{C}_6\text{H}_5\text{N} = \text{N} -\text{C}_6\text{H}_5 \, (\text{Aniline yellow}).\]
Given:
\[\text{Molar mass of aniline} = 93 \, \text{g/mol}, \quad \text{Given mass} = 279 \, \text{g}.\]
Moles of aniline:
\[n = \frac{279}{93} = 3 \, \text{mol}.\]
Mass of aniline yellow:
\[\text{Molar mass of product} = 197 \, \text{g/mol}.\]
\[\text{Mass} = 3 \cdot 197 = 591 \, \text{g}.\]
Final Answer:
\[591 \, \text{g}.\]
