We know that every gas occupy 22.4 l of volume at STP.
Here the given volume is in ml . So first we it in l
To change we divide it by 1000.
22.4 ml = 22.4 / 1000 l
=> 0.0224 l
We know that
Number of moles = Given volume / 22.4
= 0.0224 / 22.4
= 224 / 224000
= 1/ 1000
= 0.001
Number of moles is 0.001
Now ,
Number of moles = number of molecules / 6.022 × 10^23
0.001 = number of molecules / 6.022 × 10^23
=> Nunber of molecules = 0.001 × 6.022 × 10^23
= 6.022× 10^20
Here the given volume is in ml . So first we it in l
To change we divide it by 1000.
22.4 ml = 22.4 / 1000 l
=> 0.0224 l
We know that
Number of moles = Given volume / 22.4
= 0.0224 / 22.4
= 224 / 224000
= 1/ 1000
= 0.001
Number of moles is 0.001
Now ,
Number of moles = number of molecules / 6.022 × 10^23
0.001 = number of molecules / 6.022 × 10^23
=> Nunber of molecules = 0.001 × 6.022 × 10^23
= 6.022× 10^20

Answer:Na/10³
Explanation:
22.4 ml =10³ mol
1 mol=na molecules
10³ mol=10³ na molecules
