Molar Mass Comparison and Calculations

Formula Mass and Molar Mass of a Compound For my visual learners that need to see the problems worked out step by step, view the following video. You can stop watching the video at 2:55. Calculating the Molar Mass for possible chemicals 1 and 2. Calculate the Molar mass for Chemical 1: C4H10FO2P Element Number of atoms in formula Molar mass per atom Total Formula mass for element (number X atomic mass) Carbon (C) 4 12.011 48.04 Hydrogen (H) 10 1.008 10.08 Flourine (F) 1 18.998 18.998 Oxygen (O) 2 15.999 31.998 Phosphorus (P) 1 30.974 30.976 Now you will calculate the total Molar mass by adding all of values in the last column. Remember that the only difference between molar mass and Formula mass is the fact that formula mass is in the units amu ( atomic mass unit), and molar mass is in the unit of grams per mole (g What is the Molar mass for chemical 1? (Round to the 2nd decimal place. 140.09 g Calculating the Molar Mass for possible chemical 2. Calculate the Molar mass for Chemical 1: C5H11N2O2P Element Number of atoms in formula Molar mass per atom Total Formula mass for element (number X atomic mass) Carbon (C) 5 12.011 60.055 Hydrogen (H) 11 1.008 11.088 Nitrogen (N) 2 14.007 28.014 Oxygen (O) 2 15.999 31.998 Phosphorus (P) 1 30.974 30.976 Chemical 2: Now you will calculate the total Molar mass by adding all of values in the last column. Remember that the only difference between molar mass and Formula mass is the fact that formula mass is in the units amu ( atomic mass unit), and molar mass is in the unit of grams per mole (g What is the Molar mass for chemical 2? (Round to the 2nd decimal place. 162.131g
