$\qquad \quad \large {\pmb{ \frak { \mid {\overline{ \underline{\purple{ \bigstar \: Required \: Answer \: \bigstar}}}}}} \mid}\\$

We are given –

Mass of
$\bf N_2O$ is 216.6 g and we are asked to find number of moles present in 216. 6 g of
$\bf N_2O$

$\qquad$
$\pink{\bf\longrightarrow { Molar \:mass \:of \: N_2O:-} }$

$\qquad$
$\bf \twoheadrightarrow 14* 2+ 16$

$\qquad$
$\bf \twoheadrightarrow 44$

$\qquad$ ____________________

Calculating the number of moles present in 216.6 g of
$\bf N_2O$

$\qquad$
$\purple{\sf\longrightarrow { No \:of \:moles = (Given \:mass)/(Molar\: mass)}}$

$\qquad$
$\bf \twoheadrightarrow (216.6)/(44)$

$\qquad$
$\bf \twoheadrightarrow \cancel{(216.6)/(44)}$

$\qquad$
$\bf \twoheadrightarrow 4.9\: moles$
