Question

find the number of atoms for 9500g of iron​

Answer 1

Atomic mass of Fe = 56 gms

56 g of Fe contains 6.022×10

23

number of atoms

Thus, 50 g of Fe contains

56

6.022×10

23

×50 number of atoms

= 0.537×10

Answer 2

Answer:

170.113 mol

Explanation:

no of moles=mass/molar mass

molar mass if iron is 55.845g/mol

given mass=9500g

no of moles=9500/55.845=170.113 mol
