Question

What is the maximum amount of kci that can dissolve in 200 g of water?

Answer 1

The solubility of KCl in water is 34.2 g per 100 g of water.

That means at STP, 34.2 g of KCl is dissolved in 100 g of water.

So, 100 g of water dissolved= 34.2 g of KCl

1 g of water dissolved=\frac{34.2 g of KCl}{100}

200 g of water dissolved=\frac{34.2 g of KCl}{100}\times 200

=68.4 g of KCl

So, the maximum amount of KCl that can dissolve in 200 g of water is 68.4 g.

Answer 2

The correct answer is 68 g
hope this helps!!
