Another characteristic property of a substance is its density, or mass per unit volume. Like its melting point, a substance's density is determined by its chemical structure. According to Sam's soap recipe, she needs 945 grams of coconut oil. To measure out the coconut oil, Sam first places a liquid measuring cup on a kitchen scale and sets the scale to 0 grams. She then pours coconut oil into the cup until the scale reads 945 grams. She notes that the total volume of the 945 grams of coconut oil is 1.05 liters. Calculate the density of coconut oil. Write your answer as a decimal. grams per milliliter

She then pours coconut oil into the cup until the scale reads 945 grams. She notes that the total volume of the 945 grams of coconut oil is 1.05 liters. Calculate the density of coconut oil. Write your answer as a decimal. grams per milliliterAlthough mass and volume are both extensive properties, their ratio is an important intensive property called density (ρρ). Density is defined as mass per unit volume and is usually expressed in grams per cubic centimeter (g/cm3). As mass increases in a given volume, density also increases. For example, lead, with its greater mass, has a far greater density than the same volume of air, just as a brick has a greater density than the same volume of Styrofoam. At a given temperature and pressure, the density of a pure substance is a constant:
densityρ=massvolume=mVdensity=massvolumeρ=mV
Pure water, for example, has a density of 0.998 g/cm3 at 25 °C. The average densities of some common substances are in Table 1.3.11.3.1. Notice that corn oil has a lower mass to volume ratio than water. This means that when added to water, corn oil will “float” (Figure 1.3.21.3.2).
