We are given –
Mass of [tex] \bf N_2O[/tex] is 216.6 g and we are asked to find number of moles present in 216. 6 g of [tex] \bf N_2O[/tex]
[tex]\qquad[/tex][tex] \pink{\bf\longrightarrow { Molar \:mass \:of \: N_2O:-} }[/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow 14\times 2+ 16 [/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow 44[/tex]

Calculating the number of moles present in 216.6 g of [tex] \bf N_2O[/tex]
[tex]\qquad[/tex][tex] \purple{\sf\longrightarrow { No \:of \:moles = \dfrac{Given \:mass}{Molar\: mass}}}[/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow \dfrac{216.6}{44}[/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow \cancel{\dfrac{216.6}{44}}[/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow 4.9\: moles[/tex]
