4.32 moles of N2 are produced by the decomposition of 2.88 mole of sodium azide.
Equation:
2 NaN3(s) ⇒ 2 Na(s) + 3 N2(g)
According to the above equation, sodium azide has the chemical formula NaN3, while nitrogen gas has the formula N2.
Therefore, if on decomposition
3 moles of N2 is created by 2 moles of NaN3
Z moles of N2 is created by 2.88 mole of NaN3
To get the value of Z, cross multiply
Z x 2 moles = 3 moles x 2.88 moles
2 moles x Z = 8.64 moles²
Divide both sides by 2 moles
2 moles x Z/2 moles = 8.64 moles²/2 moles
Z = 4.32 moles
Thus, 4.32 moles of N2 are produced by the decomposition of 2.88 mole of sodium azide.
