How many nitrogen atoms are present in volume

Assignment Help Chemistry
Reference no: EM131941044

Engineers design air bags that deploy almost instantly upon impact. To do this, an air bag must provide a large amount of gas in a very short time. Many manufacturers use sodium azide, NaN3, to produce the gas, in such a manner: 2 NaN3(s)  →  2 Na(s) + 3 N2(g)

  1. What volume of N2(g) gas is produced if 117.0 g of sodium azide is reacted at 20.2 °C and 101.2 kPa?
  2. How many molecules of N2(g) are present in this volume? (Use Avogadro's constant)
  3. How many nitrogen atoms are present in this volume?
