Sodium azide, the explosive chemical used in atuomobile airbags, is made by the following reactions:
NaNO3 + 3NaNH2 => NaN3 + 3NaOH+ NH3
If you combine 15,0 g of NaNO3 (85 g/mol) with 15.0 g of NaNH3, what mass of NaN3 is produced?
You have the equation.
Convert 15.0 g NaNO3 to moles. #moles = grams/molar mass.
Convert moles NaNO3 to moles NaN3 using the coefficients in the balanced equation.
Convert moles NaN3 to grams by
grams = moles x molar mass
Post your work if you get stuck.
