Given 23 g of potassium nitrate per 25 g of water, what temperature should create a saturated solution?

Chemistry
1 answer:
grigory [225]3 years ago
8 0

Answer:

At about 51 °C

Explanation:

Hello there!

In this case, according to the attached solubility chart of potassium nitrate, our first step for this problem is to calculate the grams of this solute in 100 g given that 23 g are soluble in 25 g of water:

\frac{23g}{25g}=\frac{x}{100g}\\\\x=  \frac{23g*100g}{25g}=92g

Thus, such solubility of 92 g in 100 g of water is exhibited at about 51 °C.

Regards!

What are the benefits of a model to demonstrate the atomic theory?
Norma-Jean [14]

Answer:

Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.

Explanation:

We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.

All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.

Andrej [43]

Circumpolar stars

Explanation:

Stars which appears to revolve around the Polaris and do not set or go below the horizon are called circumpolar stars.

In short, this stars circles the pole.

  • Circumpolar stars are not found at the equator.
  • These stars do not set and they are visible at the north poles.
  • The simply stay as the earth spins on its axis.
