The density of lithium cylinder of height 1.2 mm and diameter 15 cm with mass 0.3624 g is to be reported. Concept introduction: The density of any object is obtained when the mass of object in grams is divided by volume of an object in milliliters. So it is denoted by unit: gram per milliliter. Density is directly associated to the mass of an object. The higher the mass of the substance higher will be its density. Density is inversely associated to the volume of a substance. The lower the volume of the substance higher will be its density. Density is associated to how the particles are packed in a substance, which in turn determines its state. The state of a substance defines density. Solids are characterized by the highest and gases by the least density.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
