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.

two reasons why cryolite is used in the electrolysis of aluminium oxide. The mixture of cryolite and aluminium oxide has a lower melting point than pure aluminium oxide. This means a lower amount of energy is required to establish effective conditions for electrolysis and thus makes it more cost effective.

Answer:
hydrogen bonds are very weak and can only occur when polar covalent bonds are present
Explanation:
Hydrogen bonds are weak intermolecular interactions that occur when hydrogen is covalently bonded to a highly electronegative atom.
Owing to the difference in electro negativity between hydrogen and the highly electronegative atom, the bond is a polar covalent bond.
This hydrogen bond is a weak bond but accounts for properties such as high melting and boiling points of small molecules such as water and ammonia.
