Homework Answers
Percent yield term is meaningful with experimental results.
Theoretical yield (Theoretically possible mass of product from moles calculation) and experimental yield (also called as actual yield - which comes from after putting reaction, extraction, dry, weigh the product), molar mass of every reactant, product and sometimes catalyst also if it consumes during the reaction no more re-generated.
Percent yield = (Experimental yield / theoretical yield) x 100%

Can someone please help? Thank you.
ATOM ECONOMY: The traditional way of evaluating the efficiency of an organic reaction is to determine the percent yield of the reaction. Most organic chemists would be quite pleased with a reaction with >90% isolated yield of the target molecule. On the other hand, a yield of 30% is typically considered to be a disappointment. As a review of the concept of theoretical yield and percent yield, let's consider the following Sy2 reaction CH3CH2CH2CH2OH...

We know that there are different disk allocation methods that help the operating system decide how disk blocks are allocated for files. In the contiguous disk allocation method, each file occupies a set of consecutive addresses on the disk. While this makes file allocation easier, an increase in the file size means that it has to be assigned elsewhere on the disk. The linked disk allocation method requires including a pointer in the current file, which points to the location...

Need help solving these questions
We are evaluating a project that costs $837,790, has an eight-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 62,239 units per year. Price per unit is $36, variable cost per unit is $19, and fixed costs are $424,751 per year. The tax rate is 35%, and we require a return of 17% on this project. In percentage terms, what...
