1.) Complete the following conversions using the correct number
of significant figures, if applicable.
2 Moles of NaOH into molecules of NaOH
29.3 grams of Mo into moles of Mo
5.6 x 1024 molecules of Ag into grams of Ag
2.)
If you are combusting 2.5 grams of ethane with 2 moles of
O2 in the reaction:
2C2H6 +
7O2 à
4CO2 + 6 H2O
Determine the limiting reagent. For the limiting reagent, determine
the mass of the leftover material. Also, determine the number of
moles of CO2 which would be produced. What would be the
percent yield if only 1.2 x 10-3 moles were
produced?

Model 4: Using Moles of Limiting Reagent in Stoichiometry The above pictures are not realistic because they involve so very few molecules. In a "real-world" sample, you are likely to have on the order of 10 molecules. Consider the following: Suppose you have a reaction vessel initially containing 13.5 moles of sulfur dioxide and 11.2 moles of oxygen mol SO, required to react with all O2 = 11.2 mol O2 x 2 mol SO 22.4 mol SO, 1 mol O2...

answer please number 1) a and b and 2 and 3
Experiment 4: Limiting reagent Often reactants are added in amounts different from the proportions given by the chemical equation in such cases, only one of the reactants may be completely consumed at the end of the reaction, whereas some amounts of other reactants will remain unreacted. The limiting reactant (or limiting reagent) is the reactant that is entirely consumed or converted to product when a reaction goes to completion....
