What is the maximum amount of KCl that can disolve in 500 g of warer? The solubility of KCl is 34g/100 g H2O at 20 degrees C.
34 x (500/100) = ?
To determine the maximum amount of KCl that can dissolve in 500 g of water, we need to use the solubility information provided.
The solubility of KCl is given as 34 g/100 g of water at 20 degrees Celsius. This means that 100 g of water can dissolve 34 g of KCl at this temperature.
To find out how much KCl can dissolve in 500 g of water, we can set up a simple proportion:
34 g of KCl / 100 g of water = x g of KCl / 500 g of water
Cross-multiplying and solving for x, we get:
34 g * 500 g of water = 100 g of water * x
17,000 g·water = 100 g·water * x
Dividing both sides by 100 g of water, we find:
170 g of water = x
Therefore, the maximum amount of KCl that can dissolve in 500 g of water at 20 degrees Celsius is 170 g.
