Hi, this is my first question, and I'm working on some summer work with a friend and we stumbled upon this problem. 1. The problem statement, all variables and given/known data A sample of LSD is added to table salt (sodium chloride) given that a 1.00 g sample of a mixture undergoes combustion to reduce 1.20g of CO2, what is the mass percentage of LSD in the mixture. 2. Relevant equations This type of LSD is C24H30N30 3. The attempt at a solution We tried to balance the combustion reaction, knowing that combustion gives us the products CO2 and H20, but we can't figure out the other products and without a balanced equation we can't do the problem.
