Answer:
The formula for this is Density = Mass/Volume
Therefore:
Density = 30g/30ml
Density = 1 g/ml
However, if you need to convert ml -> L and g -> kg for the proper si unit of mass and volume ..
30ml = 0.03L ; (divide 30mL by 1000)
30g = 0.03kg ; (divide 30g by 1000)
Density = 0.03kg/0.03L
Density = 1 kg/L
