Definition of mole?
A gram mole is defined as the mass of a substance which is numerically equal to its molecular mass expressed in gram. It is also called molecular mass & denoted by M. The unit for gram-mole is gram per mole [g/mol].
How do you get gram molecular weight?
gram molecular weight = weight of one mole of the substance in grams for example 1 mole of water weighs 1 + 1 + 16 = 18 grams so gram molecularweight of water is 18g
How do I get one mole of something?
One mole of something is 6.02 x 1023 (602,000,000,000,000,000,000,000) molicules (or atoms, if appropriate) of that substance. A gram molecular weight of anything will have one mole of molecules in it. Find out what substance you need a mole of, then find it's gram molecular weight. Take that much of the material (the gram molecular weight) and you've got your mole of that stuff.
What is the gram molecular mass of hydrogen?
The gram molecular mass of H2 is 2g.
What is a avogabros number?
Avogadro's number is the number of molecules in a gram molecular weight of any substance. It is ~ 6.02 x 1023.
How many grams are in 33 moles?
Depends on how many moles of one substance, as well as its gram atomic/formula/molecular mass.
How do you find he mass of one molecule of a substance?
- 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
How do you convert from molecular mass to grams per mole?
Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.
What is the gram molecular mass of chlorine?
The gram molecular mass of chlorine is 35.4*2 because chlorine is a diatomic element
The mass of one molecule?
- 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
How do you find the mass of a molecule?
- 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
What is the random molecular of a substance is greatest when the substance is?
When the substance is condensed
