Question
There are 2.5 moles of hydrogen in a sample of aluminum acetate, Al(C2H3O2)3. How many moles of aluminum acetate are in the sample?[?] moles AI(C2H3O2)3
Solution
To find the number of moles of aluminum acetate, we need to understand the molecular formula of aluminum acetate, which is Al(C2H3O2)3. This means that for every one mole of aluminum acetate, there are 3 moles of acetate ions, each of which contains 3 hydrogen atoms. Therefore, for every mole of aluminum acetate, there are 9 moles of hydrogen.
Given that there are 2.5 moles of hydrogen in the sample, we can find the number of moles of aluminum acetate by dividing the number of moles of hydrogen by 9.
So, 2.5 moles H / 9 = 0.2778 moles of Al(C2H3O2)3.
Therefore, there are approximately 0.278 moles of aluminum acetate in the sample.
