Question

Jaką maksymalną ilość gramów azotanu (V) potasu można rozpuscic w 300g wody w temperaturze 90 C

Proszę o pomoc!!!

Answer 1

• 609g

Step-by-step explanation:

The translated question is:

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

Solution

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 maximum amount of grams of potassium nitrate (V) that can be dissolved in 300g of water at 90 °C, just multiply by the amount of water:

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