Achemistry student needs 10.00 g of isopropenylbenzene for an experiment. he has available 120. g of a 42.7% w/w solution of isopropenylbenzene in carbon tetrachloride.
calculate the mass of solution the student should use.

The mass of solution the student should use is 23.4 g.

Explanation:

Hi there!

The concentration of the solution, 42.7% w/w, indicates that there is 42.7 g of isopropenylbenzene (IPB) per 100 g of solution. Then, if the student needs 10.00 g IPB, the mass of solution the student should take will be:

10.00 g IPB · (100 g solution/42.7 g IPB) = 23.4 g solution.

Then, the mass of solution the student should use is 23.4 g.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

so what is the problem with your lab report and whats the subject of the lab report? i will you
