Determine the mass of KNO3 that dissolves in 100 grams of water at 40°C to produce a saturated solution

Chemistry

velikii [3]3 years ago
5 0
From a solubility curve the solubility of KNO3 at 40°C is about 63 g / 100 g of water.


That means that 100 g of water at 40°C can dissolve 63 g of KNO3.


A saturated solution is one that cannot dissolve more solute, because it already has reached the greatest concentration that it can hold.


Then, the mass of KNO3 that dissolves in 100 g of water is about 63 g.

Satellites equipped with ultraviolet telescopes gather data about galaxies .<br><br> TRUE OR FALSE?
Anna71 [15]

Answer:

True.

Explanation:

Here is an example: Hubble Space Telescope's launch in 1990 sped humanity to one of its greatest advances in that journey. Hubble is a telescope that orbits Earth. Its position above the atmosphere, which distorts and blocks the light that reaches our planet, gives it a view of the universe that typically far surpasses that of ground-based telescopes.

Hubble is one of NASA's most successful and long-lasting science missions. It has beamed hundreds of thousands of images back to Earth, shedding light on many of the great mysteries of astronomy. Its gaze has helped determine the age of the universe, the identity of quasars, and the existence of dark energy.

IgorLugansk [536]
In this item, I supposed, that we are determine the molar fraction of oxygen and carbon dioxide in the sample. This can be done by dividing their respective partial pressures by the total pressure of the sample.

   O2 : mole fraction = (100.7 mmHg) / (763.00 mmHg)  = 0.13

   CO2 : mole fraction = (33.57 mmHg) / (763.00 mmHg) = 0.044

Answers: O2 = 0.13
               CO2 = 0.044
