You are given 100.0 ml of a 2.0 M solution of KOH. What would be the molarity of the solution if it is diluted to a volume of 1000 ml?

0.2M

Explanation:

Data obtained from the question include:

C1 = 2.0 M

V1 = 100mL

V2 = 1000mL

C2 =?

Using the dilution formula C1V1 = C2V2, the molarity of the diluted solution can be obtained as follows:

C1V1 = C2V2

2 x 100 = C2 x 1000

Divide both side by the 1000

C2 = (2 x 100) / 1000

C2 = 0.2M

The molarity of the diluted solution is 0.2M

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!

if you need further assistance, let me know: )
