olga2289 [7]

Answer:

  • <u>609g </u>

<u></u>

Explanation:

The translated question is:

<em>What maximum amount of grams of potassium nitrate (V) can be dissolved in 300g of water at 90 °C</em>

<em></em>

<h2>Solution</h2>

<em></em>

To answer the question you need to consultate the solubiity information for potassium nitrate (V), KNO₃.

The attached table contains the solutibility table for KNO₃ at different temperatures.

At 90ºC it is 203g / 100g water.

Then, to calculate the <em>maximum amount of grams of potassium nitrate (V) that can be dissolved in 300g of water at 90 °C</em>, just multiply by the amount of water:

  • 203g / 100g water × 300 g water = 609g ← answer
