0.5mL pipette (T.D.,+/-0.0075) was used to move 0.1400mL of acetic acid (molecular weight=60.05g/mol, density 1.049g/mol) to a 25ml volumetric flask (T.C.,+/-0.08mL) and filled the rest with distilled water.

a) find the concentration of acetic acid solution (with uncertainty value and correct significant figure).

b) 2.5mL of acetic acid solution made in a) was moved using 5mL pipette (T.D., +/-0.08) to 25mL volumetric flask (+/-0.08) and rest was filled with distilled water. Find the concentration of the solution. (with uncertainty value and correct significant figure).
