Your answer would be (D), Noble Gases, or Inert Gases - The far right on the periodic table is also known as Group(0)., or Group 18 on the periodic table. Elements in this group includes, Neon(NE), Argon(AR), Krypton(KR), Xenon(XE), and Radon(RN).
Hope that helps!!!
Molar mass N₂ = 28.0 g/mol
Number of moles:
n = mass / molar mass
n = 14 / 28.0
n = 0.5 moles
1 mole N₂ -------- 22,4 ( at STP)
0.5 mole N₂ ------- ?? Liters
L = 22.4 * 0.5 = 11,2 L
hope this helps!
