if 60 grams of potassium chlorate is dissolved into 100cm3 of water at the temperature of 60 degrees celsius is the solution saturated unsaturated or supersaturated?
The School Subject is NOT "7th grade" but perhaps "Science" instead?

You can't tell without looking up the solubility of that compound. Every compound is different.
My old Chem Physics (CRC) Handbook says that 7.1 g are soluble at 25 C and 57 g are soluble at 100 C. It does not show me a graph. At 60 C, the saturation limit would be something in between, around 25 g. Therefore the solution you describe is supersaturated.
You can probably find more detailed KClO3 solubility data online. That would be a useful exercise for you.
There is a solubility graph in .doc format at

It confirms my answer.
To determine whether the solution is saturated, unsaturated, or supersaturated, we need to compare the amount of solute (potassium chlorate) that is dissolved to the maximum amount of solute that can dissolve in the given amount of solvent (water) at the given temperature (60 degrees Celsius).
1. Find the solubility of potassium chlorate at 60 degrees Celsius: You can research or refer to a solubility table to determine the solubility of potassium chlorate at 60 degrees Celsius. Let's assume that the solubility is 100 grams per 100 cm3 of water.
2. Calculate the maximum amount of solute that can dissolve in 100 cm3 of water at 60 degrees Celsius: Since the solubility is given as 100 grams per 100 cm3, we can say that the maximum amount of potassium chlorate that can dissolve in 100 cm3 of water at 60 degrees Celsius is 60 grams.
3. Compare the amount of solute dissolved to the maximum solubility: In this case, 60 grams of potassium chlorate is dissolved in 100 cm3 of water. This amount is equal to the maximum solubility. Therefore, the solution is saturated.
In conclusion, the solution is saturated because the amount of potassium chlorate dissolved in water at 60 degrees Celsius is equal to the maximum solubility of potassium chlorate in 100 cm3 of water at that temperature.
