A solution S of sulfuric acid is prepared by dissolving 49g of H2SO4 in 500 mL of distilled water. Calculate the molar concentration of the solution

given the following solution of potassium permanganate: 

C=2 mol/L

V= 500 ml

a)calculate the volume needed to prepare another solution of potassium permanganate of concentration C=0.2mol/L and V=100mL.

b)50 mL of the prepared solution are taken and 150 mL of water are added. Calculate the new concentration of the solution.

1)it is required to prepare a solution of NaCl of volume=100ml and concentration C1=0.2mol/L from another solution of NaCl of concentration C=2mol/L.

1. calculate the volume that should be used for performing the dilution.
2. the prepared solution is divided into 2 equal parts. find the molar concentration of each part
