The equation may be used when dealing with gases, but the density of the gas (and its specific volume) may change dramatically with a slight increase or decrease in temperature. Density is the ratio of the mass of an object to its volume. As a result a buoyant force pushing upwards is created from the larger pressure pushing on the bottom of the object versus the lower pressure pushing on the top. Specific gravity (also referred to as relative density) is the ratio of the density of a material compared to the density of water at 4C4\ \mathrm{\degree C}4C (39.2F39.2\ \mathrm{\degree F}39.2F). Webone for liquids with densities lighter than water Note that the relationship between specific gravity and degrees Baum is a function of the temperature. 0000007778 00000 n

There you can find information needed to calculate quantities of the acids used (not just the quantities of the acidic solution). By comparing the mass of an object relative to its size, we are studying a property called density. Dimensional analysis will be used to ensure that units cancel appropriately. All results shown will be equivalent values. If you multiply the given volume by the known density (from Table \(\PageIndex{1}\)), the volume units will cancel and leave you with mass units, telling you the mass of the sample: Start with Equation \ref{eq1} \[\text{density} = \dfrac{m}{V} \nonumber\], \[\dfrac{2.7g}{cm^3} = \dfrac{m}{7.88 \, cm^3} \nonumber\]. All times are GMT-8. You may have to account for the temperature of the liquid depending on how precise your conversion needs to be. Since materials aren't always under standard conditions, there are also tables for materials that list specific volume values over a range of temperatures and pressures. Besides, the mass of the object can be in grams, kilograms, and pounds. Because a mass of \(1 \: \text{cm}^3\) of aluminum is \(2.70 \: \text{g}\), the mass of about \(2.5 \: \text{cm}^3\) should be about 2.5 times larger. gravity is 0.2, that means that 20% of the This is called thermal expansion of water. the mass is of the solution, not HCl.
