Question

how many electrons are present in 5 kg of iron​

Answer 1

Answer:

more than 2 electrons are present in 5 kg of iron

Answer 2

Find the number of moles first

• n = m/M = 5000/56 = 89.29
• total number of Fe atoms = 89.29 x 6.022 x 10^23

• A single Fe atom contains 26 electrons , therefore , Total number or Fe atoms = 89.29x6.022x10^23 x 26

( hope u will solve for the final value )
