We are given –

Mass of
$\bf N_2$ is 57.1 g and we are asked to find number of moles present in 57.1 g of
$\bf N_2$

$\qquad$
$\pink{\bf\longrightarrow { Molar \:mass \:of \: N_2:-} }$

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

$\qquad$
$\bf \twoheadrightarrow 28$

$\qquad$ ____________________

Now,Let's calculate the number of moles present in 57.1 g of
$\bf N_2$

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

$\qquad$
$\bf \twoheadrightarrow (57.1)/(28)$

$\qquad$
$\bf \twoheadrightarrow 2.04\: moles$
