HW
Atomic mass of aluminum --> 26
Mole------> 26g
Now no. Of atoms present in one mole = Mass no. × (6.022× 10 ²³)
=> 26×(6.022×10²³)
=> 156.572×10²³ ⚛s

[@GAMERKISMAT]

32:58 ka answer 108g hai na ❓
*Maine khud se kiya hai*
Explanation:-
Mass of aluminium = 27g
Mass of 4 mole of aluminium =27×4
=108g.
And Maine galti se 4 mole ke atoms kitna hai
Vo bhi dhund liya
Explanation:-
Mass of aluminium=27g
1 mole of aluminium=6.022×10^23 ×27
=162.022×10^23
4 mole of aluminium atom =
=162.022×10^23 ×4
=648.022 ×10^23.
Ye right hai kya ❓❓ please reply 🙏🏻🙏🏻
