The molar mass of nitrogen (n2) is 28.02 g/mol. what is the mass, in grams, of 4.60 mol of n2? 0.1646.0923.4129

Answer is 128.892 g.

moles (mol) = mass (g) / molar mass (g/mol)

According to the given data,
     moles = 4.60 mol
     mass = ?
     molar mass = 28.02 g/mol

By substitution,
   4.60 mol = mass / (28.02 g/mol)
        mass = 4.60 mol x 28.02 g/mol
        mass = 128.892 g

Hence, mass of 4.60 mol of N₂ is 128.892 g.
