1. The problem statement, all variables and given/known data CH4(g) + 3cl2(g) ----> CHCl3(g) + 3HCL(g) How many grams of CH4 is needed to produce 50.0 g CHCL3 ? For this problem, I'll assume Carbon = 12 amu, Hydrogen = 1 amu, and CL = 35.5 amu. 3. The attempt at a solution See the attachment (A PDF file), for my attempt @ the solution. I think I may have the correct answer; however, I am not positive.
