The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
Answer: i think its A
step by step explanation:
I won't be able to give an exact number because we are not given with the volume of the diluent and the aliquot. In order to explain this, I can give examples.
Dilution factor is the ratio of the initial volume and the final volume. For example, if you add 0.1 mL aliquot of the stock solution to 50 mL of the diluent like water, the dilution factor is:
Dilution Factor = Vi/Vf = 0.1/(0.1+50) = 1/501
Consequently, the concentration of the sample is equal to the product of the concentration of the stock solution and the dilution factor:
Concentration of sample = 25 M * 1/501 = 0.05 M
