NaN3 is used in some automobile air bags. The impact of a collision triggers the decomposition of NaN3 as follows: 2NaN3(s) to 2Na(s) + 3N2(g). The nitrogen gas produced quickly inflates the air bag between the driver and the windshield. Calculate the volume of N2 generated at 21 degree celsius and 823 mmHg by the decomposition of 60.0g of NaN3.

    You have the balanced equation.
    2. Convert 60.0 g NaN3 to moles. moles = grams/molar mass.

    3. Using the coefficients in the balanced equation, convert moles NaN3 to moles N2.

    4. Using moles N2 from #3, use PV = nRT (n = moles) to calculate volume at the specified conditions. Don't forget to use T in Kelvin.
