Answer:
From the periodic table:
mass of nitrogen = 14 grams
This means that:
molar mass of N2 = 2*14 = 28 grams
Now, number of moles can be calculated using the following rule:
number of moles = mass / molar mass
Therefore:
mass = number of moles * molar mass
mass = 4.25*10^3 * 28
mass = 119 * 10^3 grams
