Asaturated solution of silver nitrate is prepared in 100g of water at 20c. the solution is then heated to 50c. how much more silver nitrate must now be added to obtain a saturated solution?

233 g.

Explanation:

The solubility of silver nitrate at 20.0°C is 222 g per 100 g of water.

The solubility of silver nitrate at 50.0°C is 455 g per 100 g of water.

∴ We need to add (455 g - 222 g = 233 g) of AgNO₃ to obtain a saturated solution at 50.0°C.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
