Incomplete question. The full question read;

You are analyzing water that is known to contain silver nitrate, AgNO3. You decide to determine the amount of silver nitrate using gravimetric analysis based on the reaction:

Ag+ + Cl– → AgCl

You add excess NaCl to a 100 ml sample of the water and find that 1.2 g of AgCl solid forms.

If you added excess NaCl to a 200 ml sample of water from the same source, how many grams of AgCl solid would you expect to form?

Answer:

Explanation:

<em>Remember</em>, we were first told when NaCl is added to a 100 ml sample of the water it results in the formation of 1.2 g of AgCl.

Hence, if the volume of water is increased 2x to 200 ml from 100 ml, and NaCl is added to it, then the expected number of grams should be 0.6 (1.2g/2). That is, with increased volume, the amount of dissolution of AgCl is increased.
