What is the final volume in milliliters when 0.967 L of a 32.9 % (m/v) solution is diluted to 21.0 % (m/v)? Express your answer with the appropriate units.

Final volume in milliliters, V₂ = 1515 mL

Explanation:

Initial concentration of the solution, C₁ = 32.9 %(m/V)

The initial volume in Litres, V₁ = 0.967 L

Final concentration on dilution, C₂ = 21.0 %(m/V)

The Final volume in Litres, V₂ = ?

Using the dilution formula:

C₁V₁ = C₂V₂

0.967 * 32.9 = 21 * V₂

31.8143 = 21 * V₂

V₂ = 31.8143/21

V₂ = 1.515 L

V₂ = 1.515 * 1000

V₂ = 1515 mL

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.
