Question

26. If a saturated solution of AgNO3 at 20°C contains 216 g AgNO3 per 100.0 g of water, what mass of water could

contain 725 g of this solute at the same temperature?

Answer 1

335.6g of water will hold 725 grams of silver nitrate.

Step-by-step explanation:

The saturated solution of a solvent is the solution which can't hold more of the solvent at a particular temperature and pressure under normal conditions, if more solvent are added, it will precipitate out.

Silver nitrate solution at the particular temperature and pressure contains 216 grams of silver nitrate in 100g of water.

So, 1 gram of silver nitrate is held in 100/216 grams of water.

So, 725grams of silver Nitrate is held in 100*725/216 grams of water = 335.6 grams of water.

This gives the saturated solution of silver nitrate again.
