Question

calculate the mass of 1x10²³ molecules of​

Answer 1

Answer:

example

What is the mass of a molecule CH  4

1 mole of CH  

4

​  

=6.022×10  

23

 molecules  

                          =16 gram of CH  

4

​  

 

So, 6.022×10  

23

 molecules of CH  

4

​  

=16 gram

1  molecule of CH  

4

​  

 has mass=  

6.022×10  

23

 

16

​  

=2.656×10  

−23

 

Hence option (C) is correct.
