We are given –
- Mass of [tex] \bf N_2[/tex] is 57.1 g and we are asked to find number of moles present in 57.1 g of [tex] \bf N_2[/tex]
[tex]\qquad[/tex][tex] \pink{\bf\longrightarrow { Molar \:mass \:of \: N_2:-} }[/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow 14\times 2 [/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow 28[/tex]
[tex]\qquad[/tex]____________________
Now,Let's calculate the number of moles present in 57.1 g of [tex] \bf N_2[/tex]
[tex]\qquad[/tex][tex] \purple{\bf\longrightarrow { No \:of \:moles = \dfrac{Given \:mass}{Molar\: mass}}}[/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow \dfrac{57.1}{28}[/tex]
[tex]\qquad[/tex][tex] \bf \twoheadrightarrow 2.04\: moles[/tex]
