Question

Which sample contains the greatest number of atoms. A sample of Ca that contains 3.40×1024 atoms or a 1.76 mole sample of Be?

The sample of _____ contains the greatest number of atoms.

Answer 1

The sample of __Ca___ contains the greatest number of atoms

Step-by-step explanation:

As we know,

1 mole
`= 6.022*10^(23)` molecular entities (Can be atom, ions or molecules)

Number of atoms in 1.76 mole sample of Be

`= 6.022*10^(23) *1.76\\= 1.059 * 10^(24)`

The sample of __Ca___ contains the greatest number of atoms
