Accepted Answer
To calculate the theoretical weight of sodium borohydride needed to reduce 75 mg of benzil, we need to consider the stoichiometry of the reaction. Here's how you can approach it:
1. Balanced Chemical Equation: Write the balanced chemical equation for the reduction of benzil (C14H10O2) by sodium borohydride (NaBH4). This will tell you the mole ratio between the reactants.
2. Molar Masses: Determine the molar masses of benzil and sodium borohydride.
3. Moles of Benzil: Convert the mass of benzil (75 mg) to grams and then to moles using the molar mass.
4. Moles of NaBH4: Use the mole ratio from the balanced equation to calculate the moles of sodium borohydride needed to react with the moles of benzil you calculated.
5. Mass of NaBH4: Convert the moles of sodium borohydride to grams using its molar mass. This will give you the theoretical weight needed.
