Density of potassium salts in water is plotted as function of wt%, mol/kg water and mol/l solution.ĭensities of Aqueous Solutions of Inorganic Sodium SaltsĬhanges in density of aqueous solutions with changes in concentration at 20☌. Density of inorganic chlorides in water is plotted as function of wt%, mol/kg water and mol/l solution.ĭensities of Aqueous Solutions of Inorganic Potassium SaltsĬhanges in density of aqueous solutions with changes in concentration at 20☌. Variations in crude oil density are shown as function of temperatur, together with volume correction factors.ĭensities of Aqueous Solutions of Inorganic ChloridesĬhanges in density of aqueous solutions with changes in concentration at 20☌. Online API to Specific Gravity calculator. Molweight, melting and boiling point, density, pKa-values, as well as number of carbon and hydrogen atoms in molecules are given for 150 different alcohols and acids.ĪPI expresses the gravity or density of liquid petroleum products. Material properties of gases, fluids and solids - densities, specific heats, viscosities and more.Īlcohols and Carboxylic Acids - Physical Data Pipe lines - fluid flow and pressure loss - water, sewer, steel pipes, pvc pipes, copper tubes and more. You can divide pounds per cubic foot by 32.2 for a rough value in slugs.ĭensities of solids, liquids and gases. ![]() Note that even if pounds per cubic foot is often used as a measure of density in the U.S., pounds are really a measure of force, not mass. So it is possible that different amounts of water could have the same density.Ethyl Alcohol (Ethanol, pure alcohol, grain alcohol or drinking alcohol) The bucket with less mass has less volume. Students may point out that the bucket with more water has more mass but a greater volume. Could both the small and large amounts of water your classmate lifted have the same density?.But students may realize that they should somehow find the mass and volume of the water. It is meant as a lead-in to the investigation. Students are not expected to be able to fully answer this question at this point. How do you think you can find the density of a liquid like water?.Because D=m/v, water must also have density. Students should realize that water has volume and mass. Do you think a liquid, like water can have a density? In Lessons 1 and 2, you found the density of solids, by measuring their mass and volume.The bucket containing more water has more mass. Ask the student volunteer which bucket appears to have more mass.Select a student to lift both buckets of water.Half-fill one bucket and add only about 1 cup of water to the other. ![]() Two identical buckets or large containers.Students will be able to explain that since any volume of water always has the same density, at a given temperature, that density is a characteristic property of water. Students will be able to measure the volume and mass of water and calculate its density. Students make a graph of the relationship between the volume and the mass of water. Then they measure the mass of different volumes of water and discover that the density is always the same. Students measure the volume and mass of water to determine its density. The density of a substance is the same regardless of the size of the sample.The density of water is 1 gram per cubic centimeter. ![]()
