# Question #3470c

##### 1 Answer

#### Explanation:

A solution's **mass by volume percent concentration**,

In your case, a **for every**

You know that the solution has a total volume of

#2 color(red)(cancel(color(black)("L"))) * (10^3color(white)(.)"mL")/(1color(red)(cancel(color(black)("L")))) = 2 * 10^3# #"mL"#

which means that it must contain

#2 * 10^3 color(red)(cancel(color(black)("mL solution"))) * overbrace("1.7 g TSP"/(100color(red)(cancel(color(black)("mL solution")))))^(color(blue)("= 1.7% m/v TSP solution")) = color(darkgreen)(ul(color(black)("34 g TSP")))#

in order to have the desired mass by volume percent concentration.

The answer is rounded to two **sig figs**.

Remember, you can use the known percent concentration of a solution as a **conversion factor** because solutions are *homogeneous mixtures*, which means that they have the same composition throughout.
