Answer to Question #202951 in General Chemistry for mimi

Question

50.00 cm3 of a 1.5784 mol.dm-3 solution of potassium hydroxide is transferred to an empty 700.00 cm3 volumetric flask. This flask is made up to the mark with distilled water and then shaken well. The concentration of the potassium hydroxide in this second flask is:

Answer 1

The initial concentration, (C₁)=1.5784 mol.dm^-3

The initial volume, (V₁)=50 cm³

The final volume, (V₂)=700.00 cm³

The final concentration, (C₂)=????

 Using the following formula to calculate C₂.

Therefore the final concentration=0.1127 mol.dm^-3
