Question

Difference in between gram atomic mass and atomic mass defination

Answer 1

Gram atomic mass is the mass in grams of one mole of atoms in a mono atomic element. or The atomic mass of an element expressed in grams is called gram atomic mass. For example Nitrogen is 14 grams. The quantity of the element which weighs equal to its gram atomic mass is called One gram atom of that element. Vapor density: It  is the density of a vapor in relation to that of hydrogen. Or It is also defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen.   vapor density = molar mass of gas / molar mass of H2 vapor density = molar mass of gas / 2.016 vapor density = ~½ × molar mass
