When solving stoichiometry problems, you are often required to "invert" the molar mass of at least one of the compounds that you're working with. Select the two best descriptions of the term "invert" as it is used in our problems. (2 points) Responses Inverting means to "flip" instead of g/mol you'll have mole/grams as your units. Inverting means to "flip" instead of g/mol you'll have mole/grams as your units. Inverting means to "subtract" the masses of the elements that make up the compound. Inverting means to "subtract" the masses of the elements that make up the compound. Inverting is like "using the reciprocal" for a fraction. Inverting is like "using the reciprocal" for a fraction. Inverting the molar mass means to multiply by the number of coefficients in the problem.

The two best descriptions of the term "invert" as it is used in stoichiometry problems are:

  1. Inverting means to "flip" instead of g/mol you'll have mole/grams as your units.
  2. Inverting is like "using the reciprocal" for a fraction.

These options correctly describe the mathematical operation of taking the reciprocal of a value, which is essential when converting between moles and grams in stoichiometric calculations.
