if the initial water level in the graduated cylinder is 21.2 ml and the level rises to 27.7 ml after the object is placed in the cylinder, what is the volume of the object?
Identifying dipolar ions, There is a question in my textbook that reads P-amino acid is not a dipolar ion, whereas glycine (aminoacetic acid) is not a dipolar ion- how do you account for this?
Calculate the concentrations of the protoneated and unprotonated forms of bromothymol blue in 100 mL of a pH 8.1 buffer solution to which 1.0 mL of 0.005 M solution of bromothymol blue in 80% wate/20%ethanol has been added.
