I hope that's help and have a great night !

To find the molarity of the solution, we need to use the formula:

Molarity (M) = moles of solute / volume of solution (in liters)

First, let's calculate the number of moles of NaCl using its molar mass (MM):

Mass of NaCl = 1.00 gram

Molar mass of NaCl = 58.5 g/mol

Moles of NaCl = Mass of NaCl / Molar mass of NaCl

= 1.00 g / 58.5 g/mol

≈ 0.0171 mol

Next, we need to convert the volume of the solution from milliliters (mL) to liters (L):

Volume of solution = 415 mL = 415 / 1000 L

= 0.415 L

Now, we can calculate the molarity:

Molarity (M) = moles of solute / volume of solution

= 0.0171 mol / 0.415 L

≈ 0.0412 M

Therefore, the molarity of the solution is approximately 0.0412 M.

The closest answer option is c. 4.12 x 10^-2 M.

I hope this explanation helps! Let me know if you have any further questions.

Final answer:

It's easier for elements with low ionization energy to form cations. Examples include elements in the first group of the periodic table such as Lithium and Sodium. As more electrons are removed from an atom, the ionization energy increases due to stronger electrostatic attraction.

Explanation:

In the context of ion formation, it is easier for an element with low ionization energy to form a positive ion or a cation. Ionization energy is the minimum amount of energy required to remove an electron from an atom in its ground state. Elements with low ionization energy can easily lose an electron to form cations as the energy required to remove the electron is not high.

For example, elements in the first group of the periodic table, such as Lithium (Li), Sodium (Na), and Potassium (K), have relatively low ionization energies and thus, easily lose their one valence electron to form cations. On the contrary, elements with high ionization energies have a stronger hold on their electrons and are thus less likely to lose an electron and form a positive ion.

Furthermore, the successive ionization energies for a single element always increase. This is because removing an electron from an already positively charged ion or cation requires more energy due to the stronger electrostatic attraction that the ion has for its electrons. This makes it progressively harder to remove additional electrons, and create ions with higher positive charges.
