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?

• AP chemistry -

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.
