Final answer:
The density of the yellow liquid is 1.4 g/ml, and the density of the green liquid is 2 g/ml.
Step-by-step explanation:
The mass of the yellow liquid is 2.8 g and its volume is 2 ml. The mass of the green liquid is 6 g and its volume is 3 ml.
To find the density, we can use the formula:
Density (D) = mass (m) / volume (V)
For the yellow liquid: Density = 2.8 g / 2 ml = 1.4 g/ml
For the green liquid: Density = 6 g / 3 ml = 2 g/ml
