Answer:
<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
Answer:
1.44 L
Explanation:
If the temp does not change
P1V1 = P2V2
1 * 3.6 = 2.5 * V2
V2 = 1.44 L
Answer:
a compound
Explanation:
A molecule with multiple atoms is compound like water it's made up of 1 oxygen and two hydrogen.
25/2 and 96/X
CROSS MULTIPLY.
2x=2,400.
divide by 2.
x=1,200.
you take the GIVEN MASS of an element, and you put it on top, the coefficient is what it’s over. i believe this is right
