Aluminum has a density of 2.70 g/mL2.70 g/mL. Calculate the mass (in grams) of a piece of aluminum having a volume of 267 mLmL . Express your answer to three significant figures. Iron has a density of 7.86 g/cm37.86 g/cm3 (1 cm3=1 mL1 cm3=1 mL). Calculate the volume (in dLdL) of a piece of iron having a mass of 4.94 kgkg . Note that the density is provided in different units of volume and mass than the desired units of...
The mass unit associated with density is usually grams. If the volume (in mL or cm3) is multiplied by the density (g/mL or g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 2.00 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3
Determine the volume of an object that has a mass of 55.6 g and a density of 9.3 g/cm3.
Compute the density in g/cm3 of a piece of metal that has a mass of 0.450 kg and a volume of 52 cm3.
An ethanol-water solution is 40.00% ethanol by mass and has a density of 0.9450 (g/cm3) at 25.00°C. The density of pure ethanol is 0.7850 (g/cm3) and the density of pure water is 0.9970(g/cm3) at this temperature. At these conditions, the partial molar volume of ethanol is 55.00 (cm3/mol) and the partial molar volume of water is 17.5 (cm3/mol). a. Calculate the total volume of a 1000.0 g solution assuming both ideal and non-ideal conditions. b. What does the difference between...
