Question

Calculate the no.of molecules present in 32g of oxygen

Answer 1

no molecules in 1 mole of oxygen = 32 g of O2 =6×10^23

Answer 2

Answer:

Explanation:

1 mole of gas contains 6.022×10  

23

 molecules

No. of moles in 32 g of oxygen gas =  

16

32

​  

=2

So, the no. of molecules of Oxygen gas that are present in 2 moles of oxygen gas = 1.2044×10  

24

 

No. of moles in 14 g of nitrogen gas =  

28

14

​  

=  

2

1

​  

 

So, the no. of molecules of Nitrogen gas that are present in  

2

1

​  

 moles of oxygen gas = 3.011×10
