Question

which has more atomic mass ,100gm of sodium or 100gm of irons (Given , atomic mass of Na =23u,Fe=56u)​

Answer 1

Explanation:

100 gram of sodium has more no. of atoms

Answer 2

hey buddy here is your answer

the atomic mass of iron is greater than the atomic mass of sodium

but i guess your question should be which has more moles

gram atomic mass of sodium(Na)= 23 gm

moles of sodium in 100 gm of sodium=100/23=4.34 moles

gram atomic mass of iron(Fe)= 56 gm

moles of iron in 100 gm of iron=100/56=1.78 moles

hence 100 gm of sodium has more moles than 100 gm of  iron
