The atomic mass is the mass of an atom at rest. This refers to one atom, and is typically measured in so-called Atomic Mass units, and describes a single isotope of that element. The atomic weight is the abundance-weighted average mass of an element (an average mass of all the isotopes that exist for that element, weighted by how abundant each isotope is in nature). Atomic weight is commonly reported in atomic mass units, as well as in grams per mole. The molar mass is the mass of one mole of something, and can refer to both a single element as well as molecules and other compounds. The molecular weight is essentially the same thing as the molar mass except that, as the name implies, it refers to molecules rather than just elements. The molar mass and molecular weight is typically given in units of grams per mole.
The molecular weight of a compound is found by adding the atomic weights of all of the atoms in the compound. Water, for example, has a molecular weight of 18.0152 grams/mole, as there are two hydrogen atoms that each have an atomic weight of 1.00079 g/mole and one oxygen atom with an atomic weight 15.9994 grams/mole.
The difference between formula weight and molecular weight is in terms of type of compounds. Formula weight refers to the total of all atomic weights in the specific formula. Formula weight is used for ions rather than molecules. Molecular weight refers to the total of all atomic weights in the specific molecule.
please describe the difference between atomic weight and mass
The molecular weight is the sum of the atomic weights of all the atoms contained in the molecule.
The atomic weight (not molecular) of tantalum is 180,947 88(2).
It's much simpler than you're probably thinking. You use the term gram atomic weight for atoms, and the term gram molecular weight for molecules. That's all. The gram molecular weight of a molecule is the sum of the gram atomic weights of the atoms making up that molecule.
The molecular weight of oxygen is 16. Its atomic symbol is O and atomic number is 8. It is a gas in its natural state.
The atomic weight of potassium is 39,0983 g.The atomic weight of chlorine is 25,45 g.The molecular weight of potassium chloride (K + Cl) is 74,5483 g.
Its molecular weight and the atomic ratios between each pair of distinct type of atoms in the compound.
C6H12O6 is the molecular formula for sugar (glucose).Molecular mass/ molecular weight = (Number of C atoms) (Atomic weight of C) +(Number of H atoms) (Atomic weight of H) +(Number of O atoms) (Atomic weight of O) = (6) (12) + 12 (1) + 6 (16) = 180 (g/mole)
The atomic (molecular) weight of a substance is its molar mass.
Scandium chloride is ScCl3. Its molecular weight is the sum of the atoms' atomic weights: Sc is 45, chlorine is 35 (and 3 of them is 105), giving the molecular weight of 150.
Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight.You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule.Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1)16+1+1 = 18The molecular weight of water is therefore 18.-------------------------------------------------------------------------------------The atomic mass of H is 1.008, and the atomic mass of O is 16.So 1.008*2+16=18.016
molecule having high molecular weight is called macromolecule while a molecule having low molecular weight is called micromolecule
The molecular weight of FeSO4*7H2O is 278g
Copper. Copper has an atomic weight of 63.5.
The atomic mass (not molecular weight) of technetium-99 is 98,906 254 7(21).
Li2CO3 Li atomic weight is 6.94 C atomic weight is 12.00 O atomic weight is 16.0 Li2 has 6.94x2=13.88 C has 12.00x1=12 O3 has 16.00x3=48 13.88 +12.00 +48.00 ----------- 73.88 is the molecular weight....
The molecular mass of a compound is the sum of the atomic weights of the elements in this compound. Example: methane, CH4 Atomic weight of hydrogen: ca. 1,007 98 Atomic weight of carbon: ca. 12,106 The molecular mass of methane: (1,00798 x 4) + 12,106 = 16,137 92
molarity x molecular weight x volume=gram molarity= gram/molecular weight x volume abdulrazzaq
Molecular mass of CO = atomic weight of O + atomic weight of C = 28,01 g
Atomic weight: the atomic weight of an chemical element, in atomic mass units or gram atomic mass Atomic mass: the atomic mass of an isotope, in atomic mass units or gram atomic mass Molecular mass: the mass of a molecule, in atomic mass units or gram molecular mass
The molecular weight.
The atomic weight of chlorine is 35,45.The atomic weight of chlorine is approximately 35.5 g/mol. An addition of electron is a negligible weight difference. Therefore, the mass is considered to remain the same at 35.5 grams per mole.
The relative atomic weight of sodium is 23 and of chlorine is 35.5. Therefore the relative molecular weight of NaCl is 58.5.
Molecular weight of the compound will be the sum of the atomic weights of all the elements.
