Find the mass, in grams, of 4.10x1023 molecules of F2.

25.88 g of F₂.

Explanation:

From the question given above, the following data were obtained:

Number of molecules of F₂ = 4.10×10²³ molecules

Mass of F₂ =?

From Avogadro's hypothesis,

1 mole of F₂ = 6.02×10²³ molecules

Next, we shall determine the mass of 1 mole of F₂. This can be obtained as follow:

1 mole of F₂ = 2 × 19 = 38 g

Thus,

38 g of F₂ = 6.02×10²³ molecules

Finally, we shall determine the mass of 4.10×10²³ molecules of F₂. This can be obtained as follow:

6.02×10²³ molecules = 38 g of F₂

Therefore,

4.10×10²³ molecules = 4.10×10²³ × 38 / 6.02×10²³

4.10×10²³ molecules = 25.88 g

Thus, 25.88 g of F₂ contains 4.10×10²³ molecules.

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.
