Question

You are a work study student in our chemistry department. Amy, your supervisor has just asked you to prepare 250ml of 2.00M H2SO4 solution for tomorrow's undergraduate experiment. The Stock Solutions cabinet is under the Stockroom Explorer. You will find find a 2.50 liter bottle containing 17.8M H2SO4. Please prepare a flask containing 250ml of a 2.00M solution. To ensure proper credit, please write your calculations in the space given below.

Answer 1

mL1 x M1 = mL2 x M2
mL1 x 17.8 = 250 x 2.00M
Add some distilled H2O to the 250 mL volumetric flask, then pipet the value of mL1 of the 17.8M H2SO4 into the 250 mL flask adding concentrated H2SO4 cautiously. Add distilled H2O to the mark and mix thoroughly.

Answer 2

0.028 l

Answer 3

mL1 x M1 = mL2 x M2
mL1 x 17.8 = 250 x 2.00M
Add some distilled H2O to the 250 mL volumetric flask, then pipet the value of mL1 of the 17.8M H2SO4 into the 250 mL flask adding concentrated H2SO4 cautiously. Add distilled H2O to the mark and mix thoroughly.
