How many moles of koh are contained in 250 ml of a 2.0 m solution of koh

Chemistry
1 answer:
kotykmax [81]3 years ago
4 0
.5 mols
Assuming that your 2.0 m is an M for molarity
I used the formula M=number of mold/L
Converted 250mL to .250L by dividing by 1000

Elena-2011 [213]

Answer:

4 M

Explanation:

Molarity can be represented by the following ratio:

Molarity = moles / volume (L)

Since you have been given both the mass and volume, you can plug the values into the equation and solve for molarity.

Molarity = moles / volumes

Molarity = 2.0 moles / 0.50 L

Molarity = 4 M

Which of the follow describes what happpens to the kinetic energy of water when it changes from the solid state to a liquid stat
Anestetic [448]

Answer:

Kinetic energy increases.

Explanation:

In a solid, molecules do not have much room to move. They are very slow moving, which means that kinetic energy is low. In a liquid, molecules have more room to move. They are able to move faster than a solid, which means that kinetic energy is low.

From greatest to lowest kinetic energy:

gas, liquid, solid
