Problem 96

Sodium borohydride (NaBH_ ) is used industrially in many organic syntheses. One way to prepare it is by reacting sodium hydride with gaseous diborane $\left(\mathrm{B}_{2} \mathrm{H}_{6}\right) .$ Assuming an 88.5$\%$ yield, how many grams of $\mathrm{NaBH}_{4}$ can be prepared by reacting 7.98 $\mathrm{g}$ of sodium hydride and 8.16 $\mathrm{g}$ of diborane?
