an ice cube has a mass of 4.3g and a mass of 5.0mL it is placed in a 30mL of oil that has a mass of 27 g will the ice cube float or sink in the oil

density ice = 4.3/5 = .86 g/cm^3

density of that oil = 27/30 = .9 g/cm^3
the ice is less dense than the oil. It will float

Allison, I assume you meant the ice cub had a mass of 4.3 g and a volume of 5.0 mL.

To determine if the ice cube will float or sink in the oil, we need to compare the density of the ice cube to the density of the oil.

Density is defined as the mass of an object divided by its volume. Mathematically, it can be represented as:
Density = Mass / Volume

For the ice cube:
Mass = 4.3 grams
Volume = 5.0 mL

For the oil:
Mass = 27 grams
Volume = 30 mL

Now, let's calculate the densities:

Density of the ice cube:
Density = Mass / Volume
Density = 4.3 g / 5.0 mL
Density = 0.86 g/mL

Density of the oil:
Density = Mass / Volume
Density = 27 g / 30 mL
Density = 0.9 g/mL

Comparing the densities, we find that the density of the ice cube (0.86 g/mL) is less than the density of the oil (0.9 g/mL). Since the density of the ice cube is lower than the density of the oil, the ice cube will float in the oil.
