What is the molarity of a solution made by dissolving 8.0 g of naoh in 0.5 l?

- Molarity of the solution is 0.4M.

Solution:- Molarity is moles of solute per liter of solution.

8.0 grams of NaOH are in 0.5 L of solution. Let's convert grams to moles and divide by liters to get the molarity of the solution.

Calculations for moles of NaOH:

= 0.2 mol NaOH

Calculations for molarity:

= 0.4M

M stands for molarity.

So, the molarity of the NaOH solution is 0.4M.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
