What is the Molecular mass of aluminum?
Aluminum is a metallic element. It doesn't form molecules. Its atomic mass is 27u.
Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
What is the difference between formula mass and the molecular mass of a compound?
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
What is true of all macromolecules?
Macromolecules are formed from many simple molecules (monomers) and have a big molecular mass.
Is 44 amu is equal to molecular mass?
No, 44 amu (atomic mass units) refers to the average mass of an atom of an element. Molecular mass, on the other hand, refers to the sum of the atomic masses of all the atoms in a molecule. So, they are not equal.
What is the difference between atomic mass an molecular mass?
Atomic mass is defined for atoms. Molecular mass is defined for molecules or compounds. Atoms bond with each other to form compounds.
How does a blue star become a yellow star?
It can't. A blue star is a high-mass star. A yellow star has a medium mass.
Which factors does molecular speed depend on?
Molecular speed depends on temperature, molecular mass/weight, and the medium in which the molecules are moving. An increase in temperature generally increases molecular speed, while higher molecular mass tends to decrease speed. Additionally, molecules tend to move faster in lighter or less dense media.
How do you distinguish between a macro-molecular from molecular?
A macromolecule is formed from many molecules linked together in a chain and of course has a higher molecular mass.
What is the Molecular mass of aluminum?
Aluminum is a metallic element. It doesn't form molecules. Its atomic mass is 27u.

How many molecules are in a liter?
It really depends on what it is. You need to firstly know what it is, and particularly the molecular mass
How does the molecular mass affect freezing point depression?
The molecular mass of a solute affects freezing point depression because larger molecules disrupt the formation of solid crystals more than smaller molecules, leading to a lower freezing point for the solution.
What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
