200 g of solid sodium hydroxide (NaOH) are dissolved in 750 mL of water. What is the concentration of this solution?
Anastaziya [24]

Answer:

6.67 M

Explanation:

Molarity = \frac{mol}{L}

<em>Convert 200g NaOH to moles. Convert 750 mL to L.</em>

200 g NaOH x (1 mol/39.998 g) = 5.00025... mol NaOH

750 mL x (1 L/1000 mL) = 0.750 L

<em>Substitute values into the equation.</em>

Molarity = \frac{5.00025}{0.750}

Molarity = 6.667... M

Molarity = 6.67 M

A sodium atom and sodium ion have the same
Ilia_Sergeevich [38]

<u>Answer:</u>

a) number of neutrons

<u>Explanation:</u>

A sodium ion is formed when an electron is removed from a sodium atom. This means that the atom's number of electrons changes, but the number of neutrons remains unchanged.

However, as the number of electrons changes, the electric charge and the electronic structure change, which means that a sodium atom and a sodium ion do not have the same number of electrons, nor do they have the same electric charge or electronic structure.

Therefore, option a) is the correct option.
