Question

act of a collision triggers the decomposition of NaN, as follows: cube with its side length equals to 3 Osm, and if the airbag is operated at amb wide length quale or the decom X10 Sodium azide NENS I used in some automobile air bags. The impact of a collision tri NaN (5) Na t i:8). If airbag is an approximate cube with its side length temperature (25.0 and pressure of 800 mmHg, how many of NaNy is required to deploy the 2a NoN. mmHg, how many of ZON, RT 4285rm/ IL

Answer 1

The volume of the airbag is calculated:

V = a ^ 3 = (35 cm) ^ 3 * (1 L / 1000 cm3) = 42.88 L

The required moles of N2 are calculated:

n N2 = P * V / R * T = (800/760) atm * 42.88 L / 0.082 atm * L / mol * K * 298 K = 1.85 mol

The required NaN3 mass is calculated:

m NaN3 = 1.85 mol N2 * (2 mol NaN3 / 3 mol N2) * (65 g NaN3 / 1 mol) = 80.2 g
