How many grams of NaN3 are required to produce 17.4 ft3 of nitrogen gas?
1. Write the balanced chemical equation.
2. Convert 17.4 cubic feet N2 to liters. Then convert liters to moles. I assume this is at STP.
3. Using the coefficients in the balanced equation, convert moles N2 to moles NaN3.
4. Convert moles NaN3 to grams. g = moles x molar mass.
Post your work if you get stuck.
