Answer 1

Answer:10^20/6.02(10^23)= 1.66*10^-4

Explanation:

Answer 2

Answer:

$1.66\times10^{-4}mol$ are present in $10^{20}$ atoms.

Explanation:

In the given problem we are required to find the number of moles present in $10^{20}$ atoms.

To solve this problem we must know how many atoms are present in a single mole.This is best explained on the basis of Avagadro number.

For any Element/compound 1 mole consists of Avagadro number of atoms and it is mentioned below-

$N_{A}=6.023\times10^{23}$

As 1 mole contains these many number of atoms,then for our given problem,

Number of moles which contain $10^{20}$ atoms are calculated as shown below

$n=\frac{10^{20}}{6.023\times10^{23}} =1.66\times10^{-4}mol$

Therefore,$1.66\times10^{-4}mol$ are present in $10^{20}$ atoms.
