Question

calculate number of atoms of 0.5 mole of copper.​

Answer 1

Answer:

Explanation:

1 MOLE OF COPPER CONTAINS AVOGADRO NUMBER OF ATOMS :

1 MOLE = 6.022*10²³ ATOMS.

0.5 MOLES = X ATOMS

X ATOMS = 6.022*10²³*0.5

X = 3.011*10²³ ATOMS.

THEREFORE:

0.5 MOLES OF COPPER CONTAINS 3.011*10²³ ATOMS.

HOPE THIS HELPS.

Answer 2

Answer:

Given Data:

No of moles = 0.5 mol

To find out:

Number of atoms = ?

Solution:

Formula being used here is :

Number of atoms = No of moles * Avogadro's number

Now,putting values:

Number of atoms = 0.5 * 6.02 *10^23

Number of atoms = 3.01 *10^23 atoms.

So, number of atoms is 3.01 * 10^23 atoms.
