Lesson 3 molar mass of a compound

Lesson #3 – Molar Mass of a Compound

  • To find the molar mass of a compound, we need to look at ____________________

  • The molar mass ________________

  • ___________________________________molecule or formula unit of that compound.

  • Similar to balancing equations; you will have to take into consideration how many atoms of each element in a compound by ______________________________________


Sample problem 1

Sample problem 11

Sample Problem #1

  • Convert 2.40 x 1024 molecules of N2 to grams


Sample problem 21

Sample Problem #2

  • A spoonful of sugar, C12H22O11, has a mass of 10g. Calculate the number of molecules in a spoonful of sugar.


Sample problem 31

Sample Problem #3

  • To check for blockages in the digestive tract, a drink of barium sulfate is given to patients before an X-ray. X-rays can not pass through barium sulfate, it’s presence would appear on the X-ray film and a blockage would be apparent. If 0.500 mole of barium sulfate is needed, how many grams of barium sulfate will be given to the patient?
