What mass of HBO2 is produced if 0.32 mol of H2O is produced?

Answer 1

Hey Rylie! You'll need to know the reaction that is taking place in order for us to understand what amounts will be produced. My guess is you're looking at the combustion of diborane (B2H6).

If so, the reaction is:

B2H6(g) + 3O2(l) → 2HBO2(g) + 2H2O(l)

In that case, we'll have to convert from moles of water to moles of HBO2. To do this, we need to use the molar ratio that is given to us by the coefficients (numbers in front of) each compound. In this case, the ratio is 2 moles of HBO2 to 2 moles of H2O. This simplifies to 1:1, which tells us that we'll produce the same amount of BHO2 as water, 0.32 moles!
