Re-read and go back and look for A & B and then whatever A & B is solve for it and then get your answer
States of matter are determined by temperature. When the temperature is more cold, the particles move less. The colder the temperature, the more solid something becomes. Because the particles are in fixed positions, they do not move much, they are colder, and they are solid. Also, you cannot pass your hand through locked atoms. If you swipe your hand through water or gas, it parts. Solids, however, are fixed and cannot be passed by without significant force to break it.

A 25.00 ml sample of hydrochloric acid solution, HCl, is titrated with 0.0512 m NaOH solution. the volume of NaOH solution required is 21.68 ml then the molarity of the HCl solution is 0.044 M .
Calculation ,
Formula used : ...( i )
Where M is the molarity or concentration and V is the volume in ml .
concentration of hydrochloric acid solution ( ) = ?
concentration of NaOH ( ) = 0.0512 M
volume of hydrochloric acid solution ( ) = 25.00 ml
volume of NaOH ( ) = 21.68 ml
Putting the value of concentration , volume of both in equation ( i ) we get .
× 25.00 ml = 0.0512 × 21.68 ml
= 0.0512 × 21.68 ml / 25.00 ml= 0.044 M
