Investigating Combustion of Hydrogen & Boron Compound

In summary, a sample of gaseous substance composed of hydrogen and boron underwent combustion with excess oxygen, resulting in the conversion of all hydrogen into water and all boron into B2O3. Using the given information, we can find the empirical formula of the substance by calculating the mole ratio of hydrogen to boron, which is 2:1. The chemical formula of the substance is H2B, with a molar mass of 27.81 g/mol. Finally, the mass of B2O3 formed can be calculated using the mass of the substance and the mole ratio of boron to B2O3, which is also 2:1.
