Chlorine is widely used to purify municipal water supplies and to treat swimming pool water. suppose that the volume of a particular sample of cl2 gas is 8.80 l at 890 torr and 23 ∘c. how many grams of cl2 are in the sample?

Mass = 30.104 g

Explanation:

Given data:

Volume of Cl₂ = 8.80 L

Pressure = 890 torr (890/760 = 1.17 atm)

Temperature = 23°C (23+273 = 296K)

Mass of chlorine = ?

Solution:

PV = nRT

n = PV/RT

n = 1.17 atm × 8.80 L / 0.0821 atm. L. k⁻¹.mol⁻¹ × 296K

n = 10.296 atm. L / 24.30  atm. L.mol⁻¹

n = 0.424 mol

Mass of chlorine:

Mass = number of moles × molar mass

Mass = 0.424 mol  × 71 g/mol

Mass = 30.104 g

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.
