Answer 1

1mole nitrogen is 14g
4 mole of all= 52

Answer 2

Question :-

What is the mass of

(a) 1 mole of nitrogen atoms?

(b) 4 moles of aluminium atoms (Atomic mass of aluminium = 27)?

Answer :-

(a) Mass of 1 mole of nitrogen atoms = 14 g

(b) 4 moles of aluminium atoms

Mass of 1 mole of aluminium atoms = 27 g

∴ Mass of 4 moles of aluminium atoms = 27 x 4 = 108 g
