Question

Calculate the ratio of 5g of magnesium and 5g of iron

Answer 1

Answer:

7:3

Explanation:

No of atoms=No. of moles × atomicity × N(6.02×10^23)

No. of Mg atoms = (5/24)×1×N

No. of Fe atoms= (5/56)×1×N

ratio(Mg:Fe)= (5/24)×1×N/ (5/56)×1×N

=7/3

hence answer is 7:3

Answer 2

Answer:

7:3

Explanation:

no.of atoms=no.of moles×atomicity

N(6.02×10^23)

No. of mg atoms=(5/24)×1×N

No. of Fe atoms=(5/56)×1×N

ratio(Mg:Fe)= (5/24)×1×N/ (5/56)×1×N

=7/3

hence answer is 7:3
