Challenge Problems
Push your limits with advanced challenges
Calculate the grams of CO2 produced when 10 grams of C3H8 are completely combusted. The balanced equation is C3H8 + 5 O2 -> 3 CO2 + 4 H2O.
💡 Hint: Remember to use molar mass for conversions.
If 100 g of NaCl dissolves in water and reacts with silver nitrate (AgNO3) to form silver chloride (AgCl), what is the maximum mass of AgCl that can be produced?
💡 Hint: Check your molar masses and remember the law of conservation of mass.
