How many moles of sulfuric acid H2So4 are contained within 157 g of sulfuric acid?

The answer to your question is 1.6 moles of H₂SO₄

Explanation:

Data

moles of H₂SO₄ = ?

mass of H₂SO₄ = 157 g

Process

1.- Calculate the molar mass of H₂SO₄

Molar mass = (1 x 2) + (32 x 1) + (16 x 4)

                   = 2 + 32 + 64

                   = 98 g

2.- Use proportions and cross multiplication to find the moles of H₂SO₄

                      98 g of H₂SO₄ 1 mol

                    157 g of H₂SO₄ x

                            x = (157 x 1) / 98

                            x = 157 / 98

-Result

                           x = 1.6 moles of H₂SO₄

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.
