Sara measured the amount of potassium nitrate (KNO3) that could be dissolved in 100 grams of water at different temperatures. She repeated the test five times. The data from Sara's experiment is listed in the table below.

Temperature Mass of KNO3 in 100 g Water Average Mass
KNO3
Trial 1 Trial 2 Trial 3 Trial 4 Trial 5
0°C 12.8 g 12.9 g 13.2 g 12.7 g 13.1 g 12.9 g
20°C 31.9 g 32.1 g 32.3 g 31.8 g 31.7 g 32.0 g
40°C 62.8 g 64.3 g 64.1 g 63.8 g 64.5 g 63.9 g
60°C 108.6 g 111.4 g 111.1 g 109.7 g 109.2 g 110.0 g
80°C 168.9 g 169.9 g 169.2 g 168.4 g 167.1 g 168.7 g

Which of the following is the best inference Sara could make based on her data?
A.
There is not enough information provided to make any inferences about the solubility of KNO3.

B.
Temperature has no effect on the amount of KNO3 that can dissolve in water.

C.
The amount of KNO3 that can dissolve in water increases as temperature increases.

D.
The addition of KNO3 causes the temperature of the water to increase.

There is not enough information provided to make any inferences about the solubility of KNO3, is the best inference Sara could make based on her data.

What is the Solubility of KNO3?

Potassium nitrate is a chemical compound with the chemical formula KNO ₃. It is an ionic salt of potassium ions K⁺ and nitrate ions NO₃⁻, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter. It is a source of nitrogen, and nitrogen was named after niter.
The only way to determine the solubility of potassium nitrate is to do an experiment or interpolate from a solubility graph.
Potassium nitrate appears as a white to dirty gray crystalline solid. Water soluble. Noncombustible, but accelerates the burning of combustible materials.

The best inference Sara could make based on her data is There is not enough information provided to make any inferences about the solubility of KNO3.
