We can use the following equation to calculate the concentration of diluted solution.
c1v1 = c2v2
where c1 is concentration and v1 is volume of stock solution, which is the more concentrated solution.
c2 is concentration and v2 is the volume of diluted solution.
substituting the values in the equation,
0.188 M x 25.0 mL = c2 x 150.0 mL
c2 = 0.0313 M
concentration of diluted solution is 0.0313 M
Answer:
Since all the acid molecules have split into ions, there will be more H+ ions in a strong acid than a weak acid, hence it's pH is lower! E.g. Hydrochloric acid HCl, nitric acid HNO3. If one mole of an acid is neutralised by 2 moles of NaOH, then the acid is dibasic!

good day
thank u ✌️
Scientists were able to confirme that organism would be made of cells because they could see the cells in the tissue placed under the microscope so without the microscope they would of never known if the theory was true

Answer:
Explanation: The answer is B. Because meiosis process produce genetically different, haploid cells. Also, meiosis basically happen to produce gametes. Gametes is haploid. So, the answer is B
