Default Organic Chemistry Problem- percent yield?



I forget how to calculate percent yield.We started with 1.5 ml of distilled h20, 1.0 ml of concentrated sulfuric acid and added 1.0 of 2-methyl-2-butanol. We ended with .386 g of 2-methyl-2-butene. Any help would be appreciated

Hi,
First you want to normalize by moles so you have to divide the volume by the molecular weight and multiply by the density. Divide your product by the molecular weight to get it's value in moles. Now divided the moles of product/moles of sm and multiply by 100. You could probably also google this to get the answer.

Default Re: Organic Chemistry Problem- percent yield?

well let me make it simple
theoratically and according to the reaction
1mole of 2-methyl-2-butanol will give 1mole of 2-methyl-2-butene
u can find each number of mole since for the first
no of mole = concentration * volume..............n1
and the second
no of mole = mass/Molar Mass.....n2
then Yiled = n2/n1 * 100
Hope this helps
