Answer 1

Answer:

in 16 g of oxygen there are 6.022×10²³ /2 molecules

as mass of O2 is 32 so there are 3.011×10²³ molecules

Answer 2

Answer:

There are 6.02 into ten raise to power 23 particles in 16.0g of oxygen...

Step by step explainatio.:

1...No.of particles of oxygen is equal to mass divided bymolar mass by avogadro's no....
