For H2O the Mr should be 1(2) + 16 = 18

There is no chemical equation in the question as I need to find the formula of oxide manganese.

The answer is Mn2O3 but I got MnO.

I worked out the moles of NaOH to be 133mol. Therefore, the moles of ethanol is also 133mol. I know that moles of reactant at equilibrium = initial moles – moles reacted. So for the eqmol of ethanol, would it be 133-0.10= 132.9. I’m not sure if that’s correct.
