How many molecules of ch4 are present in .41 moles

6.56g

Explanation:

No of moles = mass given/molar mass

Molar mass of ch4

C is carbon which is 12

H is hydrogen which is 1

Molar mass= 12+4(1)

Molar mass= 16g/moles

No of moles given is 0.41moles

No of moles = mass given/molar mass

Mass given = molar mass × no of moles

Mass given = 16×0.41

Mass= 6.56g

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.
