Preparation of standard stock solution

[Nanu Nana]

Homework Statement

In this experiment we will create a standard stock solution from lyphochek serum. The concentration of proteins in serum Lyphochek is 6,8 g / dl. Pipette 1.36 mL Lyphochek serum in a 25 mL volumetric flask and dilute with physiological water. Calculate the standard stock solution concentration that you will make.

Homework Equations

c=n/v[/B]

The Attempt at a Solution

6,8 g/dl = 0,068 g/mL
0,068 g/mL x 1,36 mL = 0,09248 g / 25 mL = 0,0036992 g/mL
369,92 mg/ dl is the answer

is this answer correct ?? [/B]

Logic is OK, but where did you got so many significant figures from?

 

[Nanu Nana]

Significant figures doesn't really matter here I think

370 is all you'll ever need.
Are you forced to use horrible, unnecessary dL units?

Not really . I just wanted to know if my calculation was correct or not
