Gram to Gram mole Conversions

True/False: Before you begin, you must be sure your equation is balanced

• True

• False

Converting from gram A to gram B, the first step is to

• Convert from mole A to mole B

• Convert from mole B to gram B

• Convert from gram A to mole A

When converting from gram to gram, how many steps are there

• 1

• 2

• 3

• 4

When you multiply for each step you are using a fraction, called a

• conversion factor

• percentage

• multiplier

• prefix

To remember steps, no matter what.....what always goes in the upper left and bottom right of our conversion factors

Converting from grams C₂H₁₈ to grams CO₂ , the first conversion factor has grams of what on the bottom

• C₂H₁₈

• CO₂

• O₂

• H₂O

The middle conversion factor is the

• mole ratio of C₂H₁₈ to CO₂

• molar mass of CO₂

• molar mass of O₂

• combination lock of your locker

The third conversion factor has what on the top

• g C₂H₁₈

• mol C₂H₁₈

• g CO₂

• mol CO₂

The last step is to cancel out units, then

• multiply top times top, bottom times bottom, then divide

• cross multiply

• add up all of the conversions

• look at your neighbor's answer.....NO, DON'T CHEAT
