How many grams of potassium chlorate are needed to saturate 100g of water at 70 celsius? Group of answer choices 48 g 100 g 34 g
marissa [1.9K]

Answer:

34g of potassium chlorate.

<em> </em>

The solubility of potassium chlorate in water at 70°C is 34g/ 100g of water.

<h3>34g of potassium chlorate.</h3>
