How many grams of KClO3 can dissolve in 10g of water at 25C?

The solubility of KClO3 in water at 25C is approximately 7.5g per 100g of water.

Therefore, in 10g of water at 25C, the maximum amount of KClO3 that can dissolve is:

(7.5g/100g) * 10g = 0.75g

So, 0.75 grams of KClO3 can dissolve in 10g of water at 25C.
