Question

Fill out the following table for the scenarios of A – E:

A) 0.1g of red dye is placed in a graduated cylinder and the volume isbrought up to 100 mL

B) The entire volume of that graduated cylinder is added to a beaker and100 mL more water is added bringing the final volume (HINT – V2) to200 mL

C) 50mL is added to the beaker containing the 200 mL of solution

D) All but 100 mL of solution C is removed. To this volume and additional100 mL of water is added to this solution.

E) 50 mL of solution D is added to a new beaker. 200 mL of water isadded to this new beaker

Explanation / Answer

Grams of dye total mLsolution Concentration(% m/v) A 0.1g 100ml 0.1% B 0.001g 100ml+100ml = 200ml 0.0005% C 0.000005 50ml+200ml = 250ml 0.000002% D 0.00000002 250-100ml = 150ml+100ml = 250ml 0.000000008% E 0.00000000008 250ml-50ml = 200ml+200ml = 400ml 0
