How many atoms of mercury are in 50.15 g of mercury?

please mark brainliest

Explanation:

The correct answer to this question is 0.2500 mol

Formula to calculate moles:

Moles = mass ÷ molar mass (n=m/M)

Mass = 50.15g

Atomic mass: 200.59 amu

Moles = 50.15g/200.59

= 0.2500 mol.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
