How many moles is 1.81 x 10^24 atoms of carbon?

Answers

Well a number you have to know is 6.02 x 10^23. That is how many atoms there are in a mole.

So if you have 1.81 x 10^24 atoms,
you divide that by 6.02 x 10^24 moles to get 3 moles

Using factor/label method:
1.81 x 10^24 atoms * 1 mol
                                   ------------------------   = 3 moles
                                   6.23 x 10^23 atoms
(As you can see, the unit "atoms" cancels out from the top and bottom.)

what are the three molecules that are attached to the plasma membrane, and what are their roles/ functions?

Answers

Answer:

Ans:

*Carbohydrates

*Proteins

*Cholesterol

Explanation:

The plasma membrane is a structure that has several distinct roles in the cell

The plasma membrane is mainly composed of the phospholipid Bilayer, which is a layer of two sheets located in the internal and external parts. The Phospholipids are said to be Amphipathic because they have both properties of Hydrophobic and hydrophilic

*The Carbohydrate Molecules attach to the Plasma Membrane such as to the lipids and Proteins:

when They attach to the Proteins, they are known as glycoproteins, and they help in cell recognition, when they attach to the lipids, they are known as Glycolipids

*Protein Molecules play an important role in transport system such as Carrier Proteins

*Cholesterol Molecules help in balancing the Fluidity of the plasma membrane
