Answer: The concentration of hydrochloric acid in the final solution is 0.72 M
Explanation:
According to the dilution law,
where,
= molarity of stock solution = 3.95 M
= volume of stock solution = 268 ml
= molarity of diluted solution = ?
= volume of diluted solution = 803 ml
Next, you take 100.00 ml of that solution and dilute it to 184 ml in a volumetric flask.
According to the dilution law,
where,
= molarity of stock solution = 1.32 M
= volume of stock solution = 100 ml
= molarity of diluted solution = ?
= volume of diluted solution = 184 ml
Thus concentration of hydrochloric acid in the final solution is 0.72 M
Answer:
This question is incomplete.
Explanation:
This question is incomplete. However, an atom (as shown in the attachment) is made up three main sub-parts/basic parts namely; protons, neutrons and electrons.
A proton is positively charged and it's found in the nucleus of the atom.
A neutron has no charge and is also found in the nucleus of the atom.
Both the proton and neutron contribute to the mass of an atom; hence the mass number of an atom is the addition of the neutrons and protons. The nucleus is located at the center of the atom (usually represented with a dot) and it's positively charged because it contains just the proton and the neutron.
An electron is negatively charged and it's found orbiting the nucleus of the atom.
NOTE: The atom in the attachment is that of a helium atom. There are two labels there; however, one of those labels (nucleus) is the standard representation for two basic parts of atom (protons and neutrons) as explained earlier.
