Which liquid will float on water? Liquid A – 25 mL weighs 22.3 grams. Liquid B- 30 mL weighs 33.3 grams Liquid C- 10 mL weighs 10.001 grams.
Determine the density of each. density = mass/volume. The liquid with a density less than 1.00 (the density of water) will float.
A piece of copper wire has a density of 8.9 g/cm3. What is the density of a chunk of copper that has a mass of 250 grams?
To determine which liquid will float on water, we need to understand the concept of density. Density is the measure of how much mass (grams) fits in a given volume (milliliters). An object with a lower density than water will float while an object with a higher density will sink.
To find the density of each liquid, we can use the formula:
Density = Mass / Volume
For Liquid A:
Density = 22.3 grams / 25 mL = 0.892 grams/mL
For Liquid B:
Density = 33.3 grams / 30 mL = 1.11 grams/mL
For Liquid C:
Density = 10.001 grams / 10 mL = 1.0001 grams/mL
Now, we compare the density of each liquid to the density of water, which is approximately 1 gram/mL.
Liquid A's density (0.892 g/mL) is less than that of water (1 g/mL). Therefore, Liquid A will float on water.
Liquid B's density (1.11 g/mL) is greater than that of water (1 g/mL). Therefore, Liquid B will sink in water.
Liquid C's density (1.0001 g/mL) is very close to that of water (1 g/mL). Since the densities are almost equal, it is possible that Liquid C will neither float nor sink, but instead remain suspended in water.
So, in summary:
- Liquid A will float on water.
- Liquid B will sink in water.
- Liquid C may neither float nor sink, but rather remain suspended in water.
