4. Automotive airbags inflate when sodium azide, NaN 3, rapidly decomposes to its constituent elements according to the chemical equation, 2 NaN3 → 2 Na + 3 N2. 2 Na + 3 N2. How many moles of nitrogen are produced when 10000. milligrams of sodium azide decomposes? 0.07691142 mone a. 3.0000 moles 357 2 b. 0.15385 moles c. 0.23077 moles d. 230.77 moles​

B or 0.1538

Explanation:

Remark

For every mol of NaN3 that decomposes, 3 mols of N2 are produced.

10000 mg = 10 grams

NaN3 = 23 + 3*14

NaN3 = 23 + 42

NaN3 = 65

So set up the following proportion

10 grams / 65 = x /1      Cross multiply

10 * 1 = 65 x                  Divide by 65

x = 10 / 65

x = 0.1538 moles   which is B I think

i had this on my unit activity, i can you if you are a plato student. are you a plato student?
