Question

Number of electrons present in 44g of CO2 are (NA-Avogadro number)
1) 22x NA
2) 44x NA
3) NA
4) 2NA​

Answer 1

To find:

Number of electrons present in 44 grams of carbon dioxide.

Calculation:

In 1 molecule of CO2 , total number of electrons are 6 + 16 = 22 electrons.

So, in 1 mole of CO2 , total number of electrons are 22 × N_(A) electrons.

Now , total moles present in 44g CO2

$= \dfrac{given \: mass \: }{molar \: mass}$

$= \dfrac{44}{44}$

$= 1 \: mole$

Hence , total number of electrons present in one mole of carbon dioxide will be 22 × N_(A) electrons.

So, final answer is:

$\boxed{ \bold{ \huge{22 \times N_{A}}}}$
