The mass of 1.21 x10 20 atoms of sulfur is

Answered by wiki @


The atomic mass of sulfur is 32.07 g/mole. 
From the Avagadro constant  1 mole of a substance contains 6.022 × 10^23 particles;
1 mole of sulfur contains 6.022 ×10^23 atoms
But 1 mole is equal to 32.07 g
Therefore; 
      6.022 ×10^23 atoms = 32.07
Thus; 2.23 × 10^23 atoms = ?
       = (2.23 ×10^23 ×32.07)/ 6.022×10^23
       = 11.876 g
