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
kati45 [8]
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 N
₂ is 128.892 g.
