Given that the solubility of potassium chlorate in water is 10.0 g/100 g water at 30°C, up to 22.7 g of potassium chlorate can be dissolved in 250 g of unsaturated solution.
The solubility of potassium chlorate in water is 10.0 g/100 g water at 30 °C, that is, we can dissolve up to 10.0 g of potassium chlorate in 100 g of water at 30 °C.
At 30 °C, if a solution contains 100.0 g of potassium chlorate (solute) and 100 g of water (solvent), the mass of the solution is:
[tex]m_{solution} = m_{solute} + m_{solvent} = 10.0 g + 100 g = 110 g[/tex]
At 30 °C, 110 g of solution can hold up to 10.0 g of solute. The maximum mass of solute that can be held by 250 g of the solution is:
[tex]250 g Solution \times \frac{10.0gSolute}{110gSolution} = 22.7 g Solution[/tex]
Given that the solubility of potassium chlorate in water is 10.0 g/100 g water at 30°C, up to 22.7 g of potassium chlorate can be dissolved in 250 g of unsaturated solution.
