For our uv-via Lab our sample concentrations were diluted to 2.0 x 10^-5 M so that they could be read by machine. Calculate the quantity of each of our samples(in grams) needed to make the desired concentration in 100 ml. Hint: molecular weight of benzophenone is 182.22 grams/mol and the molecular weight of iron chloride is 162.20 grams/ mol. What is grams of benzophenone needed and the gram of iron chloride needed ?

In order to calculate the amount of initial solution to be diluted to 100 ml with the concentration of 2.0 x 10^-5 M, we need to know the concentration of this initial solution.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
