28.02g ------ 1 mol
X g ------------ 4.60 mol

X = (28.02×4.60)/1
X = 128,892 g

Answer: 128.9 grams

Explanation: The moles of the substance is calculated by the expression :

[tex]moles=\frac{\text {given mass}}{\text {Molar mass}}[/tex]

Given :

Molar Mass of [tex]N_2[/tex]= 28.02 g/mol

moles of [tex]N_2[/tex] = 4.60

Putting in the values, we get

[tex]4.60 =\frac{\text {given mass}}{28.02g/mol}[/tex]

given mass= 128.9 grams
