Question

calculate the total number of electrons present in 1.6g of methane ​

Answer 1

Answer:

6×10^23 .. hope this helps you

Answer 2

Answer:

Gram-molecular mass of methane =12+4=16g

Number of moles in 1.6g of methane =  16 /1.6  =0.1

Number of molecules of methane in 0.1 mole=0.1×6.02×10^23  =6.02×10 ^22

One molecule of methane has 6+4=10 electrons

So,

6.02×10^23  molecules of methane have 10×6.02×10^22 =6.022×10^ 23  electrons.
