There are 6.022 x 1023 molecules per mole (Avogadro's number). As there are 7.2 x 10-3 moles of hemoglobin, the number of hemoglobin molecules would be 6.022 x 1023 molecules/mole x 7.2 x 10-3 moles = 4.3 x 1021 molecules
Answer:
gravitational
Explanation:
Potential energy that is related to an object's height above the ground is known as gravitational potential energy.
Potential energy due to the position of an object above Earth’s surface is called gravitational potential energy.

It is not possible to determine CD -

as though they have a different Ksp values their molecular dissociation is also different and they may have a close solubility values.
