limiting reagent

Before completing this section you should know:

How to calculate Molar Mass
How to move from #atoms --> grams
How to move from grams a sample to grams of another sample

Basic Steps for Finding the Limiting Reagent:

Balance the equation

Convert your quantities from grams to moles for all samples.

You are doing this because moles actually tells you how many molecules are in your sample.

Find the ratio between your samples (this ratio is obtained from the balanced equation)
