The formulaic conversion between Atomic Mass units and SI mass in grams for a single atom is:
where Mu is the Molar mass constant and NA is Avogadro's number.
The number of atoms in a mole is calledAvogadro's number, the value of which is approximately 6.022 × 1023 mol-1One mole of a substance always contains almost exactly therelative atomic mass or molar mass of that substance (which is the concept of molar mass), expressed in grams ..
>> that's all thank you!! :)) ~ ^^
The formula mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.
30 amu (atomic mass units)
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
gram atomic mass (or atomic mass) of nitrogen (N) is 14 u.
Oxygen is a non meta element. Atomic mass of it is 16.
The formula mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.
mass formula
30 amu (atomic mass units)
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
AS Zn having atomic mass 65.38, S with atomic mass 32.066 and O with mass 16 so the formula mass of ZnSO4 is 161.446 amu
No. of neutrons=Atomic mass - Atomic number
The formula of the compound and the Atomic Mass of its elements.
molecular mass
number of electrons
number of electrons
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
gram atomic mass (or atomic mass) of nitrogen (N) is 14 u.
