Answer:
34g of potassium chlorate.
Step-by-step explanation:
A saturated solution is a solution that, under a temperature, has the maximum amount of solute possible. The maximum amount that a solvent can dissolve of a solute is called solubility.
The solubility of potassium chlorate in water at 70°C is 34g/ 100g of water.
That means, to saturate 100g of water at 70°C you need yo add:
34g of potassium chlorate.
