The average molecular weight of the mixture can be calculated using this formula: MWav = x1MW1 + x2MW2
Where x is the mass fraction of the components of the mixture, in this case, copper (63.546 g/mol) and zinc (<span>65.38 g/mol). </span> x1 = 7.36 / (7.36+0.51)=0.935 x2 = 0.51 / (7.36+0.51)=0.065
So, MWav = 0.935(63.546) + 0.065(65.38) = 63.665 g/mol
<span>The chemical formula is pretty straightforward. 2KOH reacts to produce H2O and K2O. This is the balanced chemical reaction between: Solid potassium hydroxide koh decomposing into gaseous water and solid potassium.</span>
