∙ 2011-12-02 01:16:08A 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].
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
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.
The gram molecular mass of H2 is 2g.
Avogadro's number is the number of molecules in a gram molecular weight of any substance. It is ~ 6.02 x 1023.
Depends on how many moles of one substance, as well as its gram atomic/formula/molecular mass.
- 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
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.
The gram molecular mass of chlorine is 35.4*2 because chlorine is a diatomic element
- 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
- 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
