Does 1mL = 1g ????

Finally my question has been answered after sometime; thx to my dear lecturer!

1 mL is a measure of volume, while 1 g is a measure of mass. 

The property that relates these two is density, where;

density = mass/volume

for water, the density at room temp and pressure is 1 g/mL. 

Thus, ONLY for water, we can assume that 1 mL of water will 

have a mass of 1 g.

for mercury, the density is 13.5 g/mL. Therefore, 1 mL of 

mercury would weigh at 13.5 g, NOT 1 g.


These relations may help:

Volume:                    Density:
1 mL = 1 cm3               1 g/mL = 1 g/cm3
1 L = 1000 mL              1 kg/L = 1 kg/dm3
1 L = 1 dm3
1 dm3 = 1000 cm3
