Answer: 6.02x10^22 atoms
Explanation: 1.4 grams is (1.4g/28 g/mole) = 0.05 moles of N2.
(0.05 moles)*(6.02x10^23 molecules/mole) = 3.01x10^22 molecules
(3.01x10^22 molecules)(2 atoms/molecule) = 6.02x10^22 atoms
To find the mass you you need multiply its volume by its density.
6 cm^3 • 2.76 g/cm^3 = 16.56 g
