Calculate ate the number of moles of oxygen atoms in 35.2 grams of oxy

Formula to determine the number of moles is:

    -(1)

Need to determine the number of moles of oxygen atoms in 35.2 g of oxygen.

Molar mass of oxygen, =

Mass of oxygen = 35.2 g  (given)

Substituting the values in formula (1):

Since, oxygen molecule contains 2 atoms of oxygen. So,

Hence, number of moles of oxygen atom in 35.2 g of oxygen is 2.202 moles.

the product of the pressure and volume is also constant

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
