Answer : The density of the liquid is, 0.895 g/ml
Explanation : Given,
Volume of liquid = 2.68 L = 2680 ml
Mass of liquid = 2.40 Kg = 2400 g
Conversion used :
1 L = 1000 ml
1 Kg = 1000 g
Formula used :

Now put all the given values in this formula, we get density of liquid.

Therefore, the mass of the liquid is, 0.895 g/ml
