Question

Atomic Number of C is 6 and H is 1. How many electrons are present in 1.6 grams of methane ?
give solution ​

Answer 1

Answer:

6.022 × 10 ^23

Explanation:

methane CH4

1 carbon and 4 hydrogen

molar mass = 12 (1) + 1 (4) = 16 gram

moles = given mass / molar mass

= 16/ 1.6

= .1

now no of molecules in 1 mole of methane = No

where No = 6.022 × 10^ 23

no of electrons in 1 molecule = 6 + 4 = 10

no of electrons in 1 mole = No × 10

no of electrons in .1 mole = No × 10 × .1

= No

6.022 × 10 ^23
