Aluminum nitrite & ammonium chloride react to form aluminum chloride, nitrogen gas and water. What amount of aluminum chloride is present after 43g of ammonium chloride have reacted completely?
1. Write the balanced chemical equation.
2. Convert 43 g NH4Cl to moles. moles = grams/molar mass.
3. Using the coefficients in the balanced equation, convert moles NH4Cl to moles AlCl3.
4. Now convert moles AlCl3 to grams. g = moles x molar mass.
