The whole cloves are broken up to help release the eugenol during distillation.
GREYUIT [131]

The statement is False.

No, whole cloves are not broken up to help release the eugenol during distillation.

Steam distillation:

  • Live steam is used in the co-distillation technique of steam distillation to separate mixture components.
  • It works well to extract essential oil constituents with high boiling points, such as those with boiling points of 200°C. However, the oil vapors themselves are warmer—around 100°C—helping to maintain the compounds' structural integrity.
  • It enables distillation to be carried out at lower temperatures than the boiling points of the constituent parts.
  • The high-boiling essential oils are vaporized by steam, and after passing through a cooling system, the hot vapors that were formed from them condense back into a liquid along with water.
  • A two-phase distillate, consisting of a water layer and an oil layer, is created because the oils are immiscible in water.

If you have 250 mL of 0.75 M LINO2.<br> How many grams of this substance<br> would you have?
Vesna [10]

Mass of this substance = 9.928 g

<h3>Further explanation</h3>

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

So to find the number of moles can be expressed as

\boxed{\bold{n=V\times M}}

mol of substance -Lithium nitrite - LiNO₂ :

V = 250 ml = 0.25 L

M = 0.75 M

\tt n=0.25\times 0.75=0.1875

So mass of this substance -  LiNO₂ (MW=52,947 g/mol) :

\tt mass=mol\times MW\\\\mass=0.1875\times 52,947 g/mol\\\\mass=9.928~g

Mass is the measure of matter contained in a substance. It is usually determined by weighing an amount of substance on a balance or scale.

  • Mass is a fundamental quantity
  • So, the unit of mass is grams.
  • Ounce and pounds are other units but not the standard one.
  • Newton is the unit of force and weight.
