If 100 grams of potassium nitrate is dissolved in 100 cm3 of water at 60oc, a(n) solution is formed.
a. saturated
b. unsaturated
c. oversaturated
d. supersaturated

- b) unsaturated

explanations:- From solubility curve, 108 g of potassium nitrate are soluble per 100 g of water (100 cubic centimeter).

So, if exactly 108 g of potassium nitrate are dissolved in 100 of water then solution will be saturated. If less than 108 g of potassium nitrate are dissolved then solution will be unsaturated and if greater than 108 g of potassium nitrate are dissolved then solution will be super saturated.

Since, only 100 g of potassium nitrate are dissolved per 100 of water, the solution is unsaturated.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

what is the question here. i think you messed up.
