Answer:
3) 1.25
Explanation:
I had the same question and somehow got it right :)
The new volume will be determined by molarity and which will be 1.25 ml.
The volume of an object is just a measurement of how much space it takes up.
The molality refers to the moles of a solute in relation to the mass of the solvent, whereas the molarity refers to the moles of a solute in based on the volume of the solution. It can be denoted by M.
The formula of Molarity is
[tex]M_{1} V_{1} =M_{2}V_{2}[/tex]
where, M is molarity and V is volume.
Calculation of volume.
It is given that,[tex]M_{1} = 0.1 M, M_{2} =0.0025 M.[/tex]
Now, puts the value of given data in molarity equation.
[tex]M_{1} V_{1} = M_{2} V_{2}[/tex]
[tex]V_{1} = M_{2} V_{2} /M_{1}[/tex]
[tex]V_{1}[/tex] = 0.005×25/0.1 = 1.25 ml
Therefore, the correct answer will be option 3.
