Sodium borohydride (NaBH4) is used industrially in many organic syntheses. One way to prepare it is by reacting sodium hydride with gaseous diborane (B2H6). Assuming an 88.5% yield, how many grams of NaBH4 can be prepared by reacting 7.98g of sodium hydride and 8.16 g of diborane?

Question

aaronq · Answer

1.write the reaction, balance it.
2.find the number of moles of each reactant, find limiting reactant (which ever one has less)
3. use ratio of the balanced equation to find moles of product, taking into account the yield percentage
