The molar mass of ethanoic acid (acetic acid, C2H4O2) is 60.05 g mol−1
H2CO3 molar mass 62.03 g mol-1
HNO3 molar mass 63.01 g mol−1
Acetic Acid, CH3COOH, has a molecular weight of 60.05
120
The molecular weight of acetic acid (CH3COOH) can be calculated by adding the atomic weights of each element in the molecule. Carbon (C): 12.01 g/mol, Hydrogen (H): 1.01 g/mol, Oxygen (O): 16.00 g/mol Molecular weight of acetic acid = (2 x C) + (4 x H) + (2 x O) = (2 x 12.01) + (4 x 1.01) + (2 x 16.00) = 60.05 g/mol
If two substances have the same equivalent weight, it means the number of equivalents per mole is the same for both substances. Therefore, the molecular weight of these substances would also be the same, as equivalent weight is derived from the molecular weight and valence of the substance.
The molecular weight of acetic acid (CH3CO2H) can be calculated from the component atomic weights of each of the atoms present in the molecule. In this particular example (C2H4O2) there are: 2 Carbon atoms with molecular weight of 12.01 = 24.02 4 Hydrogen atoms with molecular weight of 1.008 = 4.032 2 Oxygen atoms with molecular weight of 16.00 = 32.00 Therefore the total molecular weight of Acetic acid = 60.05 grams per mole
The molecular weight of poly A chain with 100 residues can be calculated by adding the molecular weight of each residue. Since each residue is AMP (adenosine monophosphate) with a weight of 300, the total molecular weight of the poly A chain would be 300 x 100 = 30,000.
Nitrous Oxide, NO has mass of 30
yes...!
It has a molecular weight of 21,600 Daltons
molecular structur C9H8K2O4molecular weight: 258.35
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
The molecular weight of vanillideneacetone is 192.214g/mol.
