when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
What is the gram formula mass of acetic acid?
60
What is the gram atomic mass of nitrogen?
gram atomic mass (or atomic mass) of nitrogen (N) is 14 u.
What is the gram formula mass for H2O?
H2O's molar mass is 18 g/mol.
How the moleculer formula of a compound is calculated if its emperical formula is known?
The gram molecular mass of the molecule must be measured by some independent method such as freezing point depression or boiling point elevation. Then the factor by which to multiply all of the subscripts in the empirical formula to get the molecular formula is the closest integer to the ratio of gram molecular mass to the gram molecular mass of a single unit of the empirical formula.
Why can't a substance have an empirical formula of NO and a gram formula mass of 45g?
From the Periodic Table The Atomic mass of Nitrogen (N) is 14 The Atomic mass of Oxygen (O) is 16 Hence the gram formula mass of NO is 14 + 16 = 30 Now NO under certain circumstances can form N2O2 hence the gram formula mass of N2O2 = (2 x 14) + ( 2 x 16) = 28 + 32 = 60 However the empirical formula is the formula with the lowest ratio of atoms. Hence N2O2 lowest ration is NO # formula mass is 30 .
A compound with the empirical formula SN was found in a subsequent experiment to have a molar mass of 184.32 gmol. What is the molecular formula of the compound?
The empirical formula of SN has a formula unit mass of the sum of the gram atomic masses of nitrogen and sulfur, i.e., about 46.0667. The gram molecular mass given in the problem divided by this formula unit mass is about 4. Therefore, the molecular formula is S4N4.
