 * // Make a new wiki titled 14-4 Stoichiometry pt 2. //
 * //**For 3 total problems** (choose randomly so I know you didnt copy) s// // how your work by showing how to set up the problem and giving the answer. //
 * __ //Put these 3 problems at the top of your page// __
 * // For all the rest of them, just give the full answer after doing the work on scrap paper. //
 * // Example: how many grams of Na will 15 moles of NaCl produce? 2NaCl --> 2Na + Cl //2
 * 1) //(put the 4 parts here)15 mol NaCl/2 mol NaCl = x g Na/2 mol Na//
 * 2) //(put the substitution amount here) 2 mol Na = 45.98 g Na//
 * 3) //(put the answer here ) X = 344.85 g Na//
 * // Round all answers to 2 decimal places. //
