Question

which of the two will have more atoms 256g of Fe 256g mg?​

Answer 1

Answer:

Given that,  

Mass of O  

2

​  

 = 256 g

We know that,  

Number of moles = [Mass/Molarmass]

So,  

Moles of O  

2

​  

 =  

32

256

​  

=8  

Number of gram atoms = Number of moles∗Numer of atoms  

                                       = 8×2=16 gram atoms  

Thus, option A is the correct answer.
