The fact that hbo2, a reactive compound, was produced rather than the relatively inert b2o3 was a factor in the discontinuation of the investigation of the diborane as a fuel. what mass of liquid oxygen (lox) would be needed to burn 296.1 g of b2h6?

1027.62 g

Explanation:

For  :-

Mass of  = 296.1 g

Molar mass of  = 27.66 g/mol

The formula for the calculation of moles is shown below:

Thus,

From the balanced reaction:-

1 mole of react with 3 moles of oxygen

Thus,

10.705 mole of react with 3*10.705 moles of oxygen

Moles of oxygen = 32.115 moles

Molar mass of oxygen gas = 31.998 g/mol

Mass = Moles * Molar mass = 32.115 * 31.998 g = 1027.62 g
