Answer #1

1 mole of every element contains same no of atoms and that is Na Avogadro number...so THE MASS IS SAME FOR ALL ATOMS...BUT WE NEED TO SEE THAT THE SMALLEST ELEMENT HAS THE LEAST MOLAR MASS...SO 10 GRAMS OF THAT ELEMENT WILL HAVE MORE NUMBER OF MOLES WHEN COMPARED WITH THE ATOM WHICH IS LARGER THAN THAT...SO SIMPLY THE LARGEST OR THE ELEMENT WITH HIGHEST ATOMIC NUMBER WILL HAVE LEAST NO OF ATOMS.....

Kr has the highest atomic number so it will have least no of atoms..
