Answer:
1. The density of the cube is 1.03 g/mL.
2. Dish soap
Explanation:
1. Determination of the density of the cube.
From the question given above, the following data were obtained:
Mass (m) of cube = 21.7 g
Volume (V) of cube = 21 mL
Density (D) of cube =?
The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Thus, density can be expressed mathematically as:
Density (D) = mass (m) / volume (V)
D = m / V
With the above formula, we can obtain the density of the cube as follow:
Mass (m) of cube = 21.7 g
Volume (V) of cube = 21 mL
Density (D) of cube =?
D = m / V
D = 21.7 / 21
D = 1.03 g/mL
Thus, the density of the cube is 1.03 g/mL.
2. Determination of the layer of density the cube will settle in.
From the question given above,
Subtance >>>>>>>> Density
Vegetable oil >>>>> 0.91 g/mL
Grape juice >>>>>> 0.97 m/L
Water >>>>>>>>>>> 1 g/mL
Dish soap >>>>>>>> 1.03 g/mL
Maple syrup >>>>>> 1.37 g/mL
Comparing the density of the cube (i.e 1.03 g/mL) with those in the table able, we can conclude that the cube will settle in the DISH SOAP layer since they both have the same density.
