ANSWER:
Problem 125P
Automobile air bag inflate following a serious impact. The impact triggers the chemical reaction:
If an automobile air bag has a volume of 11.8 L, how much NaN3 in grams is required to fully inflate the air bag upon impact? Assume STP conditions.
Step by Step Solution
Step 1 of 3
From the given,
Initial volume of air bag = 11.8 L
1 mole = 22.4L
The conversion factor ;
Let’s calculate the number of moles of air present in 11.8 L of air bag.
