The concentration of the solution in units of molarity is 0.64 M and the concentration of the solution in terms of g/mL is 0.10976 g/mL.
<h3>What is the concentration of the solution?</h3>The measure of the amount of the solute dissolved in the given amount of the solvent or solution is said to be the concentration of the solution.
It is given by the expression,
Concentration of the solution = mass of the solute/total volume of the solution
Units: g/mL
<h3>What is the concentration of the solution in units of molarity?</h3>The concentration of the solution in units of molarity is given by the expression,
Molarity = (no. of moles of the solute)/(Volume in L)
Units: moles/L
<h3>Calculation:</h3>It is given that the solute is barium hydroxide - Ba(OH)₂
The mass of Ba(OH)₂ = 2.81 g
When in dissolved in water, the total volume of the solution = 25.6 mL
The molar mass of Ba(OH)₂ = 171.34 g/mol
Then,
No. of moles = (mass of Ba(OH)₂)/(molar mass of Ba(OH)₂)
i.e.,
No. of moles = = 0.0164 mole
Concentration = mass of the solute/total volume
I.e., C = = 0.10976 g/mL
Then the concentration of the solution in units of molarity is,
Molarity = (no. of moles)/(Volume of the solution in L)
⇒ Molarity = = 0.64 M
Therefore, the concentration of the solution in units of molarity is 0.64 M.

Answer: The mole ratio of Zn to ZnO is 3: 3.
Explanation:
According to law of conservation of mass, mass can be neither be created nor be destroyed. The mass on reactant side must be equal to the mass on product side. Thus the atoms of each element on both side of the reaction must be same.
The balanced chemical reaction is:
Here 3 moles of Zn combine with 2 moles of to give 1 mole of
and 3 moles of
. Thus the mole ratio of Zn to ZnO is 3: 3.
