CHEM 101 ACTUAL EXAM QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) ALREADY GRADED A+ NEWEST VERSION If a compound's chemical formula was experimentally determined to be 18, the chemical formula could be: CH4 NH3 H2O PCl5 - Answer H2O Use the periodic table to get the atomic masses of each element. Then you can calculate the formula mass as such: H=1.008×2=2.016 O=15.999×1=15.999 Adding these together we get 18.015, which is approximately 18. The sum...
