The air bags in cars inflate through the explosive decomposition of a solid to produce a gas. The simplified version of the reaction that takes place  in most air bags is shown. 2NaN3(s) -> 2Na(s) + 3N2(g) (a) If a typical air bag has a volume of 67.0 L when inflated, how much NaN3 (in grams) is required to inflate an air bag at STP? (b) Would you want to rely on an air bag that contained only 40.0 g NaN3? Explain.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
