(SLO #2) Density is defined as the mass of a substance divided by it’s volume. You have a white crystalline solid that you need to determine the density of. To do this you weigh a graduated cylinder containing 8.5 cm3 of kerosene and find its mass to be 126.71 g. You then transfer a quantity of the crystalline solid to the cylinder containing the kerosene (ionic substances will not dissolve in kerosene). After adding the crystalline solid, you find that the volume of the liquid kerosene rose to 15.3 cm3 and that the combined mass of the cylinder, kerosene and sample was 145.53 g. What is the density of the crystalline solid?
