Answer to Question #183971 in General Chemistry for Victor

Question

A standard airbag has 130.0 g of sodium azide (NaN3).  How many grams of dangerous sodium metal would be produced? 

Show your stoichiometry work in the tables below, including all appropriate units, for full credit.  

Answer 1

2 NaN₃ → 2 Na + 3 N₂

2 moles of NaN₃ produce 2 moles of Na

Molar Mass of NaN₃ = 65

= 130/65 = 2 moles of NaN₃

= 2 moles of Na

Molar Mass of Na = 22.99

= 22.99 × 2

= 45.98g of Na
