Question

Calculate the number of molecules in 6.50 mol of CH4

Answer 1

Explanation:

1mol = 6.02×10^23 particles

6.5 mol= 6.5×6.02×10^23=39.13×10^23 CH4 molecules

Answer 2

Explanation:

Given data: no of moles of CH4 =6.50mol

Find:no of molecules of CH4=?

no of moles= no of molecules/6.023×10 power 23

no of molecules= no of moles×6.023×10 power 23.

no of molecules=6.50×6.023×10 power 23

= 39.14×10 power 23

= 3.914×10 power 24

• Answer: no of molecules of CH4= 3.914×10 power 24
