In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
No, the sample of mercury will sink in water because the density of mercury (13.6 g/cm3) is higher than the density of water (1 g/cm3), indicating that mercury is denser than water and will not float.
The block of plastic must be less dense than the water in which it will be placed in order to float. Density is equal to mass over volume (D=m/v), so you could calculate the density of the block of plastic and of a sample of the water by dividing the weight of each sample by the respective volume of each sample. If the density of the plastic is less than the density of the water, it floats! A hint: the maximum density of fresh water occurs at 4 C∘and is equal to 1 gram per 1 milliliter. When a solute - such as salt - is added, the density of water will decrease.
If you calculate the density, you'll find that it's greater than 1, therefore it will not float on water. Or you could save yourself some time and ask when the last time you saw metal float was.
The volume of 1 ml. of water equals 1 cm3.
If it is from the same sample, yes. The density of water does vary slightly depending on temperature and any dissolved solutes.
The answer is: No. Density is a property of a substance, and doesn't depend on the size of the sample. Samples of different sizes all have the same density, as long as they're all samples of the same substance, their compositions are all the same, and the conditions are the same in every case. (Samples of ice and water have different density, because the conditions are different.)
To find the density of water at a specific temperature, you can use a reference table or formula that provides the density of water at different temperatures. Alternatively, you can measure the mass and volume of a sample of water at that temperature and use the formula density mass/volume to calculate the density.
The density of water at standard temperature and pressure is 1 gram/milliliter. The size of the sample is irrelevant. If the sample is pure, then one drop of it has the same density as a tankerful of it has.
Density is independent of the amount of material in a sample. A sample of a homogeneous substance used to find the density can have any volume. If a cm3 of the substance weighs 8.1 grams, then 10 cm3 will weigh 81.0 grams.We might consider water in a glass or bottle as an example. A small sample will have a given weight (mass) because water has a given density. Ten times that sample volume will have ten times the mass of that volume of water. The density of water does not change if we examine water in a small glass and another sample of the same water in a gallon jug.
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
The sample of solid will float in water in the table of densities, where the density of the solid is less than the density of water. This can be determined by comparing the densities of the solid and water.
it is less dense.
A sample with high density.
The **density** of a substance is defined as its mass per unit volume. We can calculate the density using the formula: [ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} ] Given that the sample has a volume of **50 cm³** and a mass of **135 g**, let's determine the density: [ \rho = \frac{135 , \text{g}}{50 , \text{cm³}} ] The calculated density is approximately **2.7 g/cm³**[^10^]. Now let's compare this value to known densities: **Gold**: Gold has a density of *19.3 g/cm³*⁷. The sample's density is significantly lower. **Pure Water**: The density of pure water is approximately **1 g/cm³** at 4.0°C (39.2°F) . The sample's density is higher than water. **Aluminum**: Aluminum has a density of *2.7 g/cm³*[^10^]. The sample's density matches that of aluminum. **Ocean Water**: Ocean water contains dissolved salts, which increase its density. Seawater density typically ranges from *1.02 g/cm³ to 1.03 g/cm³*. The sample's density is higher than seawater. Based on the calculated density, the sample is most likely **aluminum**.
density = mass / volume. so you need to weigh to find the mass. To find the volume submerse in water and record the displacement of water to find the volume.
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
