HI DEAR :)
Answer:
All the above are correct
Explanation:
THE 1MOLE of any substance is equal to. 6.022 X 10^23 molecules
Since the MOLECULAR MASS / MOLAR MASS of any compound/ element is equal to 1mole of that element .
EG :- He (molar mass )= 4
(and that will contain 6.022X 10^23 molecules = 1mole )
also, H2O (molecules mass) = 2X 1 + 16 = 18g ( and it will also contain 6.022 X 10^ 23 molecules = 1mole)
THANKS:)
All Of The Above
To Explain :-
The One mole of any substance = 6.022 × 10^23
Molecular Mass :-
Example :-
Finally :-
{ And it will also contain 6.022 × 10^23 molecules = 1 mole }
