The reaction of methane (CH 4) with Cl 2 forms chloroform (CHCl 3) and HCl. Although CHCl 3 is a general anesthetic, it is no longer used for this purpose since it is also carcinogenic. The molar masses for all substances are given under the balanced equation. CH4(g) + 3 Cl2(g) CHCl3(l) + 3 HCl(g) 16.04 g/mol 70.90 g/mol 119.4 g/mol 36.46 g/mol a. What is the theoretical yield of CHCl 3 in grams from 3.20 g of CH 4? b. What is the percent yield if 15.0 g of CHCl 3 are actually formed in this reaction?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
