Number of moles :

n = mass solute / molar mass

n = 20 / 18

n = 1.111 moles

Therefore:

Molarity  =  moles solute / volume

Molarity  = 1.111 / 30 => 0.37 M

Answer:

Throughout the explanations section below you will find a description of the question.

Explanation:

(1)

  • Whether a solution would be positioned inside a separative funnel, combined water, as well as solvent, disintegrate particulate caffeine. In every stage, the caffeine content incorporated relies upon the coefficient of caffeine partitioning throughout the combination of water as well as fluid.
  • Thus, increasingly caffeine is taken from the solvent whenever the moment you bring additional solvent. Consequently, we separate the solvent from the single component.

(2)

  • For compounds to be mixed thoroughly and separated into different layers, a shuddering mixture within the dividing funnel would be essential.
  • However, it vibrates the separation funnel forcefully, restricts airflow within the funnel, which can also induce the fluid under it to burst or causing fluid to fire.
