Question

the no of atoms in 0.1 mol of a tetra atomic gas is

Answer 1

I molecule of the gas contains 4 atoms as it is tetra atomic
so 1mole of the gas will contain
6.023×10^23 molecules
=4 × 6.023 × 10^23 atoms

So in 0.1 moles number of atoms
=0.1 × 4 × 6.023 × 10^23 atoms
=2.4092 × 10^23 atoms

HOPE IT HELPS..... :-)

Answer 2

Answer:

$2.4088\times 10^{23} atoms$ are present in 0.2 mol of tetra atomic gas.

Explanation:

Moles of tetra atomic gas = 0.1 mol

Number of molecules of tetra atomic gas  :

$0.1\times 6.022\times 10^{23}=6.022\times 10^{22} molecules$

In 1 molecule of the tetra atomic gas there are 4 atoms.

Number of atoms in 0.1 mole of a tetra atomic gas:$4\times 6.022\times 10^{22} =2.4088\times 10^{23} atoms$

$2.4088\times 10^{23} atoms$ are present in 0.2 mol of tetra atomic gas.
