Homework: page 125 problems 67, 69, 70, 71, 72, 73
Problem #70 gives you the molar mass indirectly by giving a mass amount and the number of moles associated with the mass amount. Remember, molar mass is reported as grams per mole. Reading comprehension for #73 is key to understanding the problem. The word "only" in the first sentence is key. You also have to reason with the vagueness of the real molar mass.
