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.

The nuclear symbol of the isotopes of gallium where as the symbol must be determined according to its parts and they are the symbol of the element, the atomic number of the element and also the mass number of the specific isotopes. So the symbols is Ga 42 over 71 . I hope this would help
Answer:
<em><u>A. any absorbance of light by the solvent AND the cuvette needs to be accounted for</u></em>
Explanation:
Blank calibrations are usually carried out on the spectrometer to eliminate and account for any readings that would come from absorptions of the curvette, solvents/reagents or anything that is not the main analyte we are testing for.
Hence the blank solution does not contain the analyte itself. Fingerprints should be removed from the curvette as practice. Hence the most suitable answer amongst the options is A.
I hope this was clear ad most of all, helpful.
