how to calculate atomic mass

Molecular mass is equal to sum of the atomic masses of all atoms present in one molecule of the substance.Example: H 2 OMass of H atom = 1Mass of 2H atoms = 2Mass of O atom = 16Molecular mass = 2 + 1..

Molecular mass is equal to sum of the atomic masses of all atoms present in one molecule of the substance. Example: H 2 O Mass of H atom = 1 Mass of 2H atoms = 2 Mass of O atom = 16 Molecular ma..

The mass of an electron (m) is determined by dividing the value of 'e' by e/m. Charge/mass (e/m) = 1.76 x 10 8 coulomb/g Charge (e) = 1.602 x 10 - 1 9 coulombs...

Let, The mass of the compound taken be = W g Mass of AgX formed = W 1 g From stoichiometry, Ag = X 1 mol 1 mol 1 molecular mass 1 atomic mass Therefore, ..

Let, The mass of the organic compound be = W g Mass of the precipitate of BaSO 4 = W 1 g From stoichiometry, BaSO 4 = S 1 mol 1 mol 1 molecular mass 1 atomic mass 233 g 32 g Therefore, ..

Then, Molecular mass of the acid = Equivalent mass of the acid x Basicity of the acid. The basicity of an acid is equal to the number of ionizable hydrogen atoms in a molecule of the ac..

Let, The mass of the organic compound taken be = W g Mass of Mg 2 P 2 O 7 obtained = W 1 g From stoichiometry, Mg 2 P 2 O 7 = 2P 1 mol 2 mol 1 x molecular mass 2 x atomic mass 222 g 2 x 31 g = 62 g Therefore, ..

The total number of protons and neutrons present in one atom of an element is known as its mass number. Mass number = number of protons + number of neutrons It can also be said that: Mass number = Atomic number + number of neutrons Atomic..

An indirect method to determine the absolute mass of an atom has been devised. The mass of a particular atom is taken as a standard unit and the masses of other atoms are related to this standard. Hydrogen being the lightest element and be..

Experiments have determined that the mass of an atom is very small, ranging from 1.7x10 -24 g to about 4.0x10 -22 g. It is very difficult to accurately weigh a bunch of atoms, as they are extremely light, small, and invisible; they weigh too little for us to express th..
