Graphing techniques are used extensively in science. Explain how a calibration curve could be used to determine an unknown quantity. Density is an intensive property and is very useful for identification. Explain why density allows us to identify an unknown substance. Density is also useful unit conversion for converting volume to mass or mass to volume. The density of an ethylene glycol/water mixture at 16.0 degreeree C is 1.0188 g/mL. Calculate the mass of 25.5 mL of ethylene glycol/water mixture. Calculate the volume of 20.5 g of ethylene glycol/water mixture. Explain how you would determine the density of each of the following substances. A 10 gram sphere of pure silver. A 10 gram cube of sodium chloride A 10 gram wooden rectangle of oak A 10 gram solution of isopropyl alcoholExplanation / Answer
