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.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
