Answer:
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.
<em>∴ We need to add (455 g - 222 g = 233 g) of AgNO₃ to obtain a saturated solution at 50.0°C.</em>
Answer: When an atom becomes a positive ion it pulls it's electrons closer, decreasing it's radius moreover, when it becomes a negative ion, it pulls it's electrons closer and decreases the radius
I hope this helps :)
