The solubility of sodium nitrate at 95º C in g/ 100 mL of water is 448.21.
<h3>Equation :</h3>
To calculate the solubility
Using formula,
Solubility = mass of the compound / mass of the solvent
Thus,
Known data is :
mass of the compound, sodium nitrate = 84.994 g/mol
mass of the solvent, water = 18.015 g/mol
C = 84.994 g/mol / 18.015 g/mol
C = 4.718 g/mol
By the temperature 95ºC
So,
C = 4.718 g/mol x 95ºC
C = 448.21 g/ 100 mL
<h3>Solubility :</h3>
The maximum amount of the sample that will dissolve in a given amount of solvent at a given temperature is referred to as its solubility. Different substances have very different solubilities, which is a characteristic of a particular solute-solvent combination.

Answer:
2,8,2
Explanation:
the element x has to be divalent I.e it has two electrons on its outer shell.
just look at the two at the end of 2,8,2
the compound formed is Xcl2
Answer:
Chloroethane is denser and has a higher boiling point
Explanation:
The density of a gas depends directly on the molar mass of the gas. This means that as the molar mass increases, density increases and vice versa.
Having said that, we can easily see that the molar mass of chloroethane (64.51 g/mol) is greater than the molar mass of ethane (30.07 g/mol). Hence we expect that chloroethane is denser than ethane as established above.
In the absence of other strong intermolecular forces, the higher the molecular mass of a substance the greater its boiling point. Thus the boiling point of chloroethane is higher than that of Ethane since they both have weak Van der Waals forces holding their molecules together in the gaseous state.
Answer:
D. The data supported the hypothesis
Explanation:
The data shows that rats fed a normal diet with the addition of vitamins gained a higher average weight gain in the period of 3 months, compared to rats fed a normal diet. This supports the scientists' hypothesis of "Young rats that had vitamins added to their food would gain weight faster than young rats fed a normal diet."
