Question

How many atoms are their 0.1 mol. of sodium.

Answer 1

As we know the formula
No. of moles= No. of atoms/Avogadro Number

No. of atoms = 0.1 × 6.022 × 10²³
No. of atoms= 6.022 × 10²²

Answer 2

Given,

Number of moles $=0.1 mol$

Avogadro number $=6.022*10^{23}$

To Find,

Number of atoms

Solution,

We can simply solve this chemical problem by using the chemical formula.

Formula:

Number of atoms = Number of moles $*$ Avogadro Number

Number of atoms = $0.1*6.022*10^{23}$

Number of atoms = $6.022*10^{22}$

Hence, the number of atoms in $0.1mol$. of sodium is $6.022*10^{22}$.
