sports scuba divingHow many grams of potassium chloride can be dissolved in 200g of water at 80 C?
Answer and Explanation:
This means that at 80 degrees C, the saturated solution of KCl will contain 50 grams of KCl for every 100 grams of water. Therefore, the mass of KCl that will dissolve in 200g of water at 80 degree C is equal to: Mass of KCl=50×200100=100 g Mass of KCl = 50 × 200 100 = 100 g .
Correspondingly, how many grams of potassium chloride can be dissolved in 100g of water?
Answer and Explanation: This means that at 80 degrees C, the saturated solution of KCl will contain 50 grams of KCl for every 100 grams of water.
Consequently, what is the maximum amount of KCl that can dissolve in 200 g of water at 10c?
Therefore, the maximum amount of KCl that can dissolve in 200 g of water is, 68 grams.
