<u>Answer:</u> The mass of solid NaOH required is 80 g
<u>Explanation:</u>
Equivalent weight is calculated by dividing the molecular weight by n factor. The equation used is:
where,
n = acidity for bases = 1 (For NaOH)
Molar mass of NaOH = 40 g/mol
Putting values in above equation, we get:
Normality is defined as the umber of gram equivalents dissolved per liter of the solution.
Mathematically,
Or,
......(1)
We are given:
Given mass of NaOH = ?
Equivalent mass of NaOH = 40 g/eq
Volume of solution = 400 mL
Normality of solution = 5 eq/L
Putting values in equation 1, we get:
Hence, the mass of solid NaOH required is 80 g
The complete chemical formula for the unknown compound is N2O3 where X = 2 which is the oxidation state of oxygen.
<h3>What is oxidation state?</h3>
Oxidation state is the number of electron which the compound is giving or taking from each other to form the bonds as the oxidation is hight oxidation is happening asn if the low then reduction is happening.
In the compound N2O3 the oxidation state of O is 2 and the oxidation stte of N is 3 written in the cross-cross manner in compound.
Therefore, N2O3 where X = 2 which is the oxidation state of oxygen is complete chemical formula for the unknown compound.
