Question

which has more number of atoms , 100 grams of sodium or 100 grams of iron ( given atomic mass of Na = 23 u, Fe=56 u) ​

Answer 1

Answer:

:Given, Mass of Na = 100g ; Molar mass of Na= 23 g

No. of moles of  Na =  

23*100= 4.347

No. of atoms of Na = 4.35 x avogadro no

Given, Mass of Fe = 100g ; Molar mass of Fe= 56 g

No. of moles of  Fe =  

56*100 = 2.10

No. of atoms of Fe = 2.10 x avogadro no

So, Na has more no. of atoms.
