Question

Calculate number of atoms fe which can weigh 26g

Answer 1

Explanation:

firstly we have to find the number of moles...

so, molar mass of fe is 56

then, number of moles = 26/56

➡ 0.464

to find number if atoms...

we multiply number of moles by avagadro number...

hence, number of atoms = 0.464 * 6.022*10²³

➡ 2.794 * 10²³

hope it helps... please follow... ;-)
