1. Write the equation and balance it.
2. Convert 15 g Ca to moles. moles = grams/molar mass.
3. Convert 36 g ethanol to moles.
4. Using the coefficients in the balanced equation, convert moles Ca to moles of a product.
5. Do the same for moles ethanol to the same product.
The one producing the smaller number of moles will be the limiting reagent.
