Question

1.       Assume you measured out8.010 g of n-butyl bromide. In the end you produced and recoveredonly 6.465 g of n-butyl bromide. A)calculate the number of moles of n-butyl alcohol you started with.B) Calculate the number of moles your theoreticalyield of n-butyl bromide you should have gotten (one to one ratio)C) Calculate the theoretical yield in grams ofn-butyl bromide you could have recovered. D)Calculate the number of moles of n-butyl bromide you did collect(mass 6.465 g) E) Calculate the molar percent yield of product you recovered.

Explanation / Answer

I believe that the starting material is n-butylalcohol. A molar mass n-butyl alcohol. 74.12 g/mol 8.010g/74.12g/mol=.108 mol B is the same number as A .108mol C molar mass of n-butyl bromide 137.02 g/mol .108 mol * 137.02 g/mol=14.80 g D. 6.465g / 137.02g/mol=.047 mol E .047/.108*100=43.69%
