Question

Calculate the number of electrons in 1.6 g CH4 molecule?​ With proper explanation

Answer 1

Solution :

⏭ Given:

✏ Weight of methane = 1.6g

⏭ To Find:

✏ No. of electrons in given amount of methane.

⏭ Concept:

✏ First, we have to find out moles of methane, after that we can calculate no. of electrons.

⏭ Formula:

✏ Formula of mole in terms of weight of substance and molecular weight of substance is given by

$\star \: \underline{ \boxed{ \bold{ \sf{ \pink{ \large{no. \: of \: mole = \dfrac{weight}{molecular \: weight}}}}}}} \: \star$

⏭ Calculation:

✏ Molecular weight of methane = 16g/mol

• Calculation of no.of mole

$\implies \sf \: n = \dfrac{1.6}{16} \\ \\ \implies \sf \: \red{n = 0.1}$

• Calculation of no.of electrons

✏ One molecule of methane contains 10 electrons.

$\implies\sf\:no.of\:electrons=0.1\times6.022\times10^{23}\times10\\ \\ \implies\:\boxed{\sf{\orange{no.of\:electrons=6.022\times10^{23}}}}$
