Explanation:
The functional group is an atom, group of atoms or bond which is responsible for the chemical reactions of the members of a series of organic compounds.
The chemical properties of various groups of compounds in organic chemistry depends of the concept of functional groups. They help us to classify molecules into families or groups based on a common general molecular formula.
The nature of the functional group determines the overall chemical properties of the molecule such as polarity, water solubility, and so on. Chemical reactions occur only at the functional group.
For instance, for the reaction below, reaction occurs at the functional groups as follows;
CH3COOH + CH3OH -------> CH3COOCH3
Also, during amide formation, reaction occurs between the carbonyl chloride and an amine at the respective functional groups as shown;
CH3COCl + CH3NH2 -----> CH3CONHCH3 + HCl
Density = 1.0 g/mL
5.3 (w/w)% => 5.3 / 100 => 0.053
molar mass acetic acid = 60.05 g/mol
M = 1000. w . D / molar mass
M = 1000 . 0.053 . 1.0 / 60.05
M = 53 / 60.05
M = 0.882 mol/L

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
d, one atom of oxygen and two atoms of hydrogen
