Question

Calculate the total number of electrons present in 1.6 gram of ch4

Answer 1

$\huge\red{\boxed{\bold{Solutions}}}$

• No. of moles of CH4 = 1.6/1.6 = 1

• No. of molecules in 1.6 g CH4 = 0.1 × 6.022 × 10^23

$\implies$ 6.022 × 10^22 molecules.

• 1 molecules of CH4 has 10 electrons.

• 6.022 × 10^22 molecules of CH4 has 10 × 6.022 × 10^22 electrons.

$\implies$ 6.022 × 10^23 electrons.
