Question

The number of atoms in0.1mol a tetraatomic gas is

Answer 1

Given :
Atomicity of moelucle is 4
Avogadro Number=6.022x 10²³ atoms
0.1 mole of gas available.
Number Of atoms=Mole x Avogadro number x atomicity of molecule
=0.1 x 6.022x 10²³ x 4
=2.40 x 10²⁸ atoms

∴Number of atoms in 0.1 mole of a tetra-atomic gas is 2.40 x 10²⁸ atoms
