The average chloroplast is about 3 µm (micrometers) in diameter. In one square millimeter of the surface of a leaf, there are about half a million chloroplasts.
A chlorophyll molecule consists of two parts, the porphyrin ring (head) of 15x15 Å and a phytol tail of 20 Å.

What is the molecular size of phenol?
The molecular size of phenol is relatively small. It has a molecular weight of about 94.11 grams per mole, and its molecular formula is C6H5OH.
What is size of DMSO molecule?
The molecular formula of dimethyl sulfoxide (DMSO) is C2H6OS. The molecular weight of this molecule is approximately 78.13 grams per mole. In terms of size, DMSO has a molecular diameter of about 6.9 angstroms.
Is chloroform found in a plant cell?
No, chloroform is not naturally found in plant cells. Chloroform is a synthetic chemical used in various industrial and laboratory processes.
What is the basis of molecular sieve chromatography?
Molecular sieve chromatography is based on the size exclusion principle, where smaller molecules can enter the pores of the sieve material and take longer to elute, while larger molecules are excluded and elute faster. This technique separates molecules based on their size and molecular weight.
How does molecular size affect the drug?
Molecular size can influence how a drug is absorbed, distributed, metabolized, and excreted in the body. Smaller molecules may be more easily absorbed but can have a shorter duration of action, while larger molecules may have slower absorption but longer-lasting effects. Additionally, molecular size can impact the drug's ability to cross cell membranes and interact with target molecules.
What is the molecular formula for chloroform spirit?
Chloroform , formula is 'CCl3H'. It is dissolved in a spirit, such as an alcohol. It modern IUPAC name is 'Tri-chloromethane'.
What is the molecular mass of chloroform if .0275 mol weighs 3.28 g?
The molecular mass of chloroform can be calculated using the formula: Molecular mass = Mass / Moles. Plugging in the values given, the molecular mass of chloroform is 119.27 g/mol.
Is chloroform ionic or molecular?
Chloroform is a molecular compound. It is composed of individual molecules consisting of carbon, hydrogen, and chlorine atoms connected through covalent bonds.
What percent by mass of each chloroform molecule is composed of hydrogen?
Each chloroform molecule (CHCl3) is composed of 25% hydrogen by mass. This is because the molecular weight of hydrogen is 1, with one hydrogen atom in each chloroform molecule, and the molecular weight of chloroform is 119.38.
Give the formula for chloroform?
The formula for chloroform is CHCl3, which represents one carbon atom, one hydrogen atom, and three chlorine atoms.
Can chloroform dissolved cholesterol?
Chloroform is a nonpolar solvent and can dissolve cholesterol, which is also nonpolar. This interaction occurs due to similarities in their molecular structures, enabling chloroform to effectively dissolve cholesterol.
Is chlorine bonded in chloroform through covalent bond?
Yes, chlorine in chloroform is bonded to three hydrogen atoms through covalent bonds. Chloroform has a tetrahedral molecular geometry due to these covalent bonds.
What is the polarity of chloroform?
Chloroform is considered a nonpolar molecule because it has a symmetrical tetrahedral shape due to its molecular structure, leading to equal distribution of charge and no significant dipole moment.
What percent by mass of chloroform molecule is composed of chlorine?
The molecular formula of chloroform is CHCl3. The molar mass of chlorine is about 35.5 g/mol and the molar mass of chloroform is about 119.4 g/mol. Therefore, the percent by mass of chlorine in chloroform is (35.5 g/mol / 119.4 g/mol) x 100 = approximately 29.7%.
Why acetone is easily soluble in chloroform?
Acetone is easily soluble in chloroform because both acetone and chloroform are polar organic solvents with similar chemical properties. This allows them to mix and dissolve in each other easily. Additionally, both molecules have a similar structure and molecular weight, further enhancing their solubility in one another.
Is chloroform non-polar?
Yes, chloroform is a non-polar molecule due to its symmetric molecular structure, which results in an even distribution of electron density. This makes chloroform soluble in non-polar solvents.
What is the molecular geometry or shape of chloroform CHCl3?
The molecular geometry of chloroform (CHCl3) is tetrahedral. This means that the central carbon atom is surrounded by three hydrogen atoms and one chlorine atom, with the bond angles between these atoms being approximately 109.5 degrees.
