xLof N2 GAS AT STP contains 3*1022molecules.
the number of molecules in ozone at STP will be
give the answer with complete explanation
No of molecules = No of moles x NA ( NA - Avogadro Number)
No of moles =
=
= 0.4981 x 10-1 = 0.04981 moles
1 mole of any gas occupies 22.4 L at STP
so 0.04981 mole occupy = ?
=
= 1.115 L
The volume of N2 at STP = 1.115 L
If the volume of Nitrogen and Ozone are equal,
22.4 L is occupied by 1 mole.
The no of moles of Ozone present in 1.115 L = ?
=
= 0.04981 moles
No of molecules = mole x NA
= 0.04981 x 6.023 x 1023
= 3 x 1022
No of molecules in ozone = 3 x 1022
Thus both of them have same no of molecules
No of moles =
=
= 0.4981 x 10-1 = 0.04981 moles
1 mole of any gas occupies 22.4 L at STP
so 0.04981 mole occupy = ?
=
= 1.115 L
The volume of N2 at STP = 1.115 L
If the volume of Nitrogen and Ozone are equal,
22.4 L is occupied by 1 mole.
The no of moles of Ozone present in 1.115 L = ?
=
= 0.04981 moles
No of molecules = mole x NA
= 0.04981 x 6.023 x 1023
= 3 x 1022
No of molecules in ozone = 3 x 1022
Thus both of them have same no of molecules
