To determine the density of water and NaCl solution (15%w), density = (mass/volume) can be used. The date below is obtained, when different volumes of water or NaCl were weighed at 25oC.
a) H2O
Volume (ml)    Mass (g)
5    4.985
10    10.030
15    14.955
20    19.94
25    24.925
30    29.91

b) NaCl solution (15% w)
Volume (ml)    Mass (g)
5    5.532
10    11.064
15    16.596
20    22.128
25    27.66
30    33.192
