Question

Calculate number of proton , electron and neutron in 8gm of CH4

Answer 1

TO FIND :

number of proton , electron and neutron in 8gm of CH4

GIVEN :

mass is 8 gm

WE KNOW :

Molecular mass of CH4 = 16 amu

SOLUTION :

number of moles of CH4 = weight /molecular mass

=) number of moles = 0.5

Each mole has

$6.02 \times {10}^{23}$

So 1/2 mole has 3.02 ×10²³ electrons

* Since an atom is electrically therefore number of electrons is equal to the number of protons.....
