Question

calculate the number of molecules present in 1.6gm of methane​

Answer 1

Explanation:

1mole of methane (16 grams) contains Avogadro number of molecules. 0.1moles of methane( 1.6grams) contains '0.1 x Avogadro number' of molecules. Thus 0.1 mole of CH₄ contains "10 x 0.1 x Avogadro number" of electrons. Therefore 1.6 grams of methane contains 6.022 x 10²³ electrons.
