Question

what is formula mass molecular mass and gram atomic mass?

Answer 1

The sum of mass of each element in a compound is callled as its molecular mass. units in u(unified mass)
Example for CH3 molar mass=12+3×1=15u

The sum of mass of each element in a ionic compound is callled as its formula mass ( same as molecular mass but used for ionic compounds.units in u

When the masss of compound is measure in grams per mole is called gram atomic mass(mostly for monoatomic substances).units in g/mol

Answer 2

Answer:

Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.
