Answer:
To calculate the number of molecules in 4g of oxygen, we have,
Moles of oxygen = 4/32 = 0.125mol,
Molecules of oxygen = 0.125 * 6.022 * 10^23 = 7.52 * 10^22.
Oxygen's atomic weight is 16.00 amu where 1 mole of oxygen is
6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g.

Answer:
1/8* avagardo no.
Explanation:
U see
O2 molecular mass is 32
I mole contains 6.022* 10to the power of 23
Now according to the question
The no.of moles is
4/32 that is 1/8 moles
Use cross multiplication method and get the answer
