Final answer:
Unfortunately, there is no specific data available for the solubility of silver chromate in an aqueous ammonia solution with a concentration of 2 mol/L and 25°C. Therefore, the obtained value of 6.7 g cannot be evaluated without accurate solubility data.
Step-by-step explanation:
The solubility of silver chromate in an aqueous ammonia solution can be determined by using the solubility product constant (Ksp).
However, there is no information provided regarding the specific solubility of silver chromate in an aqueous ammonia solution at a concentration of 2 mol/L and 25°C. The given value of 6.7 g for the mass of silver chromate dissolved in 100 g of the solution cannot be evaluated without accurate data on solubility.
