Convert between CH3C1 weight and moles
Elemental composition of CH3C1
|Element||Symbol||Atomic weight||Atoms||Mass percent|
|Computing molar mass step by step|
First, compute the number of each atom in CH3C1:
C: 2, H: 3
Then, lookup atomic weights for each element in periodic table:
C: 12.0107, H: 1.00794
Now, compute the sum of products of number of atoms to the atomic weight:
Molar mass (CH3C1) = ∑ Counti * Weighti =
Count(C) * Weight(C) + Count(H) * Weight(H) =
2 * 12.0107 + 3 * 1.00794 =
|Mass percent composition||Atomic percent composition|
Formula in Hill system is C2H3

Definitions of molecular mass, molecular weight, molar mass and molar weight
Weights of atoms and isotopes are from NIST article.
- Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
- Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
