In our Ochem lab for nitration of bromobenzene we didn't further seperate the product mixture of 4-bromonitrobenzene and 2-bromonitrobenzene and yet we have to calculate the percent yield of the mixed product using percent distribution. So I used .5 ml of bromobenzene and weighted .84g of mixed bromonitrobenzene product, could someone help me calculate the percent yield?
