No. The weight of a given volume of a solid is dependent on its DENSITY (weight per volume). The value provided may be its absolute density (at a given temperature) or its specific gravity(density compared to another substance, usually water).
At standard temperature.
The substance with a density of 0.647 g/cm³ is likely ethanol at room temperature. Ethanol has a density close to this value, which can vary slightly depending on temperature and impurities.
The density of a material is defined as its mass per unit volume. The density of liquid water is normally given as 1000 kg/m3 or 1 g/cm3 as a very accurate estimate, but often ranges slightly below this value, depending on temperature. Unlike other agents that tend to freezing point, water tends to expand as at freezes; it therefore becomes less dense. Thus, the density of solid water is normally given as just over 91% of this; a common given value is 9.17 g/cm, or 9170 kg/m3.
The formula for mass if density is not given is mass=volume/power
No. The weight of a given volume of a solid is dependent on its DENSITY (weight per volume). The value provided may be its absolute density (at a given temperature) or its specific gravity(density compared to another substance, usually water).
- The specific weight is the weight of a known volume of material at a given temperature and pressure; the unit of measure is kN/m3. - But if you think to relative density: Relative density (specific gravity) is the ratio between the density of the material to be tested and the density of water, at a given temperature and pressure; consequently no unit of measure for this ratio.
The density of the substance is needed to convert mass to volume in a stoichiometry problem. Density is a measure of how much mass is contained in a given volume. It relates the mass of a substance to its volume.
Yes- the highest probability value is the mode. Let me clarify this answer: For a probability mass function for a discrete variables, the mode is the value with the highest probability as shown on the y axis. For a probability density function for continuous variables, the mode is the value with the highest probability density as shown on the y-axis.
The density of a liquid should be consistent and reproducible across multiple measurements to ensure that the data are good. Typically, the density should be close to the accepted value for that particular liquid at a given temperature and pressure. Deviations from this value could indicate errors in the measurement or experimental setup.
At standard temperature.
The substance with a density of 0.647 g/cm³ is likely ethanol at room temperature. Ethanol has a density close to this value, which can vary slightly depending on temperature and impurities.
The density of phenol decreases as the temperature increases due to thermal expansion. At 20°C, the density of phenol is about 1.07 g/cm^3, and this value decreases slightly as the temperature rises. It's important to note that the density of phenol is not affected significantly by temperature changes over a typical laboratory range.
It is necessary to indicate the temperature when giving the density of liquids because temperature effects the density of many liquids. For example, water increases in density as it becomes colder.
To round density, you would take the given density value and determine how many decimal places you want to round to. If rounding to the nearest whole number, you would round the density value to the nearest whole number based on the decimal point.
737.22 kg/m^3 The density depends on a whole range of factors including purity and Temperature. Use the above as a guide though but in situations where the value of density is critical, take a sample to the lab for them to determine the correct value.
Density aka specific gravity is a measure of the amount of matter in a given volume. Actually specific gravity is not the measure of the amount of matter in a given value, it is a comparison of the density of the substance to water's density. Specific gravity is a unitless quantity.
