1.42L of the 9.0M NaOH are required

Explanation:

Molarity is an unit of concentration in chemistry defined as the ratio of the moles of a solute (In this case NaOH) and the volume of the solution.

To solve this question we must know the moles of NaOH required in 4.25L of a 3.0M NaOH as follows:

4.25L * (3.0moles / L) = 12.75 moles of NaOH are required

As all NaOH must come from the 9.0M NaOH the volume we need is:

12.75 moles NaOH * (1L / 9.0 moles NaOH) =

hi,

the answer is d, it has indefinite shape but definite volume.

hope this !
