The answer to your question is: 40.8 g of NaN₃
Step-by-step explanation:
NaN₃ mass = ?
nitrogen = 1.2 moles
Equation
2NaN₃ ⇒ 2Na + 3N2
2 moles of NaN₃ ----------------- 3 moles of N₂
x ------------------ 1.2 moles of N₂
x = (1.2 x 2) / 3
x = 2.4/ 3
x = 0.8 moles of NaN₃
MW NaN₃ = 23 + 28
= 51 g
51 g of NaN₃ ----------------- 1 mol
x ----------------- 0.8 mol
x = (0.8 x 51) / 1
x = 40.8 g of NaN₃
