help me find which reactant is the limiting reactant when 74 g NaOH and 44 g CO2 are allowed to react when the equation is (2NaOH+1CO2=Na2CO3+1H2O)

  • chemistry - ,

    1. Convert 74 g NaOH to mols. mols = grams/molar mass
    2. Convert 44 g CO2 to mols. Same rocess.
    3a. Using the coefficients in the balanced equation convert mols NaOH to mols of either product.
    3b. Do the same for mols CO2 to the same produce.
    3c. You will have two numbers for mols of the product and both can't be right. The correct answer in limiting reagent problems is ALWAYS the smaller value and the reagent producing that value is the limiting reagent.
    This is the long way of doing it but I like it better than the short way.
