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.

Answer: Hydrogen bonds
Explanation: Hydrogen bonds allow two molecules to link together temporarily. Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds.
The molar mass of H2O2 is 34 g/mol.
