Masses of many atoms are close to integral multiple of the mass of an

The atomic mass of an element is the weighted average of the atomic masses of different isotopes of that element .This explains,why atomic masses of many elements show large departures from integer values.However ,even if we consider msases of individual isotpes,they are not strictly integer multiples of the mass of a hydroen atom.How do yo account for this fact?

How many atoms are present in one gram atomic mass of a substance ?

Which one of the following polymers has molecular mass an integral multiple of molecular mass of monomer ?

What are the multiples and sub multiples of mass?

Identify the CORRECT statements. The mass of one mole of a substance in grams is called its molar mass. The formula mass of a substance is the sum of atomic masses of atoms present in the formula. One mole is the amount of a substance that contains as many entities or particles as there are atoms in exactly 12 g of the carbon-10 isotope.

In Bohr's model of an atom, which of the following is an integral multiple of (h)/(2pi) ?

Molecule mass: Calculate the molecule mass of vitamin C or ascrobic acid (C_(6) H_(8) O_(6)) using rounded values for atomic masses. Strategy: Add the atomic masses of the elements in the formula, each multipled by the number of times the element occurs.
