Recall the balanced chemical equation from part B of task 1:
2NaN3 → 2Na + 3N2.
Calculate the mass of sodium azide required to decompose and produce the number of moles of nitrogen you calculated in part B of this task. Refer to the periodic table to get the atomic weights.
part B calculation: (1.30) (58) = n (0.0821) (768)
75.4 = n (0.0821) (768)
75.4 = 63.0528 n
75.4/ 63.0528 = n
1.195 = n
