Question

Weight of 50atoms of an element is 3000acms calculate number of atom in 240gram of the elements​

Answer 1

Explanation:

Given, Mass of 50 atoms=3000amu

⇒ Mass of 1 atom=

50atom

3000amu×1atom

=60amu

⇒1atom=60amu

Mass of 1 mole of atoms=60gms

Now, given 240gm of element

No. of moles of atoms in 240gm of element is

60g

240g×1mole

=4 moles

Now, We know 1 mole of atoms has 6.023×10

23

atoms

⇒4 mole of atoms have

1mole

4mole×6.023×10

23

atoms

=24.092×10

23

atoms

∴240gm element has 24.092×10

23

atoms
