10cm^3 of solution b is added to a beaker.
distilled water is added to the beaker until the final volume in the beaker is 100cm^3
the ph of the solution is measured before and after distilled water is added.
table 4 sows the results(im jus going to write wats in the table):

| volume of solution in beaker: | ph of solution: |
| 10cm^3 | 3 |
| 1000cm^3 | x |
calculate the value of x

can someone me on this question plz, i feel like its easy, but i just forgot how to do it lol

4.0.

Explanation:

∵ pH = - log[H⁺] = 3.

∴ log [H⁺] = - 3.

∴ [H⁺] = 0.001 M.

no. of millimoles before the dilution = no. of millimoles after the dilution

(MV) before dilution = (MV) after dilution

∴ M after dilution = [H⁺] = (MV) before dilution/ V after dilution = (10.0 cm³)(0.001 M)/(100.0 cm³) = 0.0001 M.

∴ pH of 100.0 cm³ solution = - log[H⁺] = - log(0.0001) = 4.0.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
