What is the molarity of a solution containing 5 moles of solute in 250 milliliters of solution?

The molarity of a solution is 20 M

Explanation:

Molarity is defined as the number of moles present in one liter of solution.

Mathematically,

We are given:

Moles of solute = 5 moles

Volume of solution = 250 mL

Putting values in above equation, we get:

Hence, the molarity of a solution is 20 M

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
