You have a stock solution of 175 mu g/mu\\ of DNA. If you want to make 175 mu | of a solution with a concentration of 17.50 mu g/mu | of DNA, you would need to mix _ mu| of your stock with _ mu | of your solute. Put your first answer below. Your second answer should be the answer to the subsequent question. Answers cannot contain more than one decimal place. If your answer is a whole number, put .0 after the whole number.

Solution

WE know V1S1=V2S2

SO HERE S1=175 ug/ul

V2=175ul

S2=17.50

So V1=17.5ul [(175*17.50)/175]

So from the stock 17.5ul needs to be taken and mix it with 175-17.5=157.5ul of solute to make the final concentration of the desired DNA strength.
