The expectancy of how long a product will last divided by two!
The solubility of potassium chloride in at room temperature is approximately 34 g per 100 g of water. Therefore, the maximum amount that could be dissolved would be 34/100 ( 200) = 68 g of KCl. When more than this amount is added, excess potassium would not dissolve forming crystals in the solution.
It depends. many of the websites i see answering the questions are all over the place, but good luck.
The answer would be 1,3,1,3
