One way to synthesize diborane, B 2 H 6 , is the reaction (a) If you have 0 136 g of NaBH 4 and excess H 3 PO 4 , and you collect the resulting B 2 H 6 in a 2 75 L flask at 25C, what is the pressure of the B 2 H 6 in the flask (b) A by product of the reaction is H 2 gas If both B 2 H 6 and H 2 gas ...

To solve this problem we can use the ideal gas law which relates the pressure volume amount of substance and temperature of a gas The ideal gas law is ...

Question:

One way to synthesize diborane, B₂H₆, is the reaction

2 NaBH4(s) + 2 H3PO4(l) BH6(g) + 2 NaHPO4(s) + 2 H(g)

(a) If you have 0.136 g of NaBH₄ and excess H₃PO₄, and you collect the resulting B₂H₆ in a 2.75-L flask at 25°C, what is the pressure of the B₂H₆ in the flask?
(b) A by-product of the reaction is H₂ gas. If both B₂H₆ and H₂ gas come from this reaction, what is the total pressure in the 2.75-L flask (after reaction of 0.136 g of NaBH₄ with
excess H₃PO₄) at 25°C?
