Nitrogen gas and sodium liquid are produced by the decomposition of sodium azide NaN3 (s). what volume of nitrogen gas, measured at 25 C and 0.980 atm, is produced by the decomposition of 62.5 g of sodium azide

Answer 1

Write the equation and balance it.
Convert 62.5 g NaN3 to mols. mol = g/molar mass.
Use the coefficients to convert mols NaN3 to mols N2 gas.
Use PV = nRT to convert n to volume at the conditions listed.
