The molecule pentaborane(9) (mol. mass 63.14) was once thought to be a candidate for rocket fuel. It spontaneously reacts with O2(g) as shown below to generate high temperatures and expanding gaseous products. 2 B5H9(g) + 12 O2(g) → 5 B2O3(s) + 9 H2O(g) What pressure would build up in a 500. mL storage tank if 5.00 g of pentaborane reacted with excess O2(g) that leaked into the tank and the temperature increased to 400. °C?

Question
The molecule pentaborane(9) (mol. mass 63.14) was once thought to be a candidate for rocket fuel. It spontaneously reacts with O2(g) as shown below to generate high temperatures and expanding gaseous products.
2 B5H9(g) + 12 O2(g) → 5 B2O3(s) + 9 H2O(g)
What pressure would build up in a 500. mL storage tank if 5.00 g of pentaborane reacted with excess O2(g) that leaked into the tank and the temperature increased to 400. °C?
