Consider the stoichiometry of the reaction provided in the question(s) below. a. A laboratory student started with 0.0812 grams of Reactant A (benzaldehyde, m.w. 106.12 g/mol). How many millimoles of Reactant A did the student add to the reaction mixture? b. A laboratory student started with 0.162 grams of Reactant B (sodium chromate, m.w. 161.97 g/mol). How many millimoles of reactant B did the students add to the reaction mixture?
Consider the stoichiometry of the reaction provided in the question(s) below.
a. A laboratory student started with 0.0812 grams of Reactant A (benzaldehyde, m.w. 106.12 g/mol). How many millimoles of Reactant A did the student add to the reaction mixture?
b. A laboratory student started with 0.162 grams of Reactant B (sodium chromate, m.w. 161.97 g/mol). How many millimoles of reactant B did the students add to the reaction mixture?
c. Which of the reactants is the limiting reagent?
d. After running the reaction, the student isolated 0.0733 grams of signal product (benzoic acid, m.w. 122.12 g/mol). How many millimoles pf product did the student isolate?
e. calculate the % yield of this reaction
A) Given mass of benzaldehyde=0.0812 g
Molar mass of benzaldehyde = 106.12 g/mol
Moles of reactant A = 0.0812/106.12 = 0.00765 moles
1 moles = 1000 millimoles
MilliMoles of reactant A= 7.65 mmoles
