Question

kclo3
how many grams of kclo3 will dissolve in:
note: remember that the solubility curve graph is designed using 100 g of water.
17 fill in the blank 1 point
50 g of water at 60 °c
answer
25 g 60 g 12 g
previous

Explanation:

Step1: Determine solubility at 60°C

From solubility - curve knowledge (usually shows solubility of a substance in 100 g of water at different temperatures), assume the solubility of KClO₃ in 100 g of water at 60°C is 25 g (if we assume the value based on a typical KClO₃ solubility - curve).

Step2: Calculate solubility in 50 g of water

Set up a proportion. Let x be the mass of KClO₃ that dissolves in 50 g of water. We know that $\frac{x}{50}=\frac{25}{100}$. Cross - multiply gives $100x = 25\times50$, then $x=\frac{25\times50}{100}=12.5\ g$. Since we are choosing from the given options, the closest value is 12 g.

Answer:

12 g
