Which of the following has the maximum number of atoms?

Options

A. (a)`24 " g of" C(12)`
B. (b)`56 " g of" Fe(56)`
C. (c )`27 " g of o Al" (27)`
D. (d)`108 " g of Ag" (108)`

Answer

A

Explanation

(a) `24 g` of `C(12)` has maximum number of atoms.
Number of atoms in `24 g` of `C=24/12xx6.023xx10^(23)`
`=2xx6.023xx10^(23)` atoms
(b) Number of atoms in `56 g` of `Fe =56/56xx6.023xx10^(23)`
`=1xx6.023xx10^(23)` atoms
(c ) Number of atoms in `27 g` of `Al=27/27xx6.023xx10^(23)` atoms
`=1xx6.023xx10^(23)` atoms
(d) Number of atoms in `108 g` of `Ag=108/108xx6.023xx10^(23)`
`=1xx6.023xx10^(23)` atoms
