Question

9.72 g of potassium chloride is dissolved in 30g of water at 70 degree celcius.Calculate the solubility of potassium chloride at that temperature

Answer 1

Answer:

100/30*9.72

=32.4 kg

This is the answer but you write in process.

Answer 2

Answer: The solubility of potassium chloride at the given temperature is 32.4 g/100 g

Explanation:

Solubility is defined as the amount of solute that can be dissolved in 100 grams of solvent.

We are given:

Amount of potassium chloride dissolved in 30 grams of water = 9.72 g

To calculate the mass of potassium chloride that can be dissolved in 100 g of water, we use unitary method:

In 30 grams of water, amount of KCl dissolved is 9.72 grams

So, in 100 grams of water, amount of KCl dissolved will be = \frac{9.72g}{30g}\times 100=32.4g

30g

9.72g

×100=32.4g

Hence, the solubility of potassium chloride at the given temperature is 32.4 g/100 g
