Unformatted text preview: scale, we will use Equation (l.3): TF + 40 9P--=-Tc + 405C TF + 40 = TF + 40 = 9F-196C + 40-156C 5C 9F T, + 40 = -(-156C) =-281F F 50C TF =-281F-40 =-321F SEE EXERCISES 1.53, 1.55, AND 1.56 J..8 ~ Density A property of matter that is often used by chemists as an &quot;identification tag&quot; for a sub-stance is density, the mass of substance per unit volume of the substance: mass Density = volume The density of a liquid can be determined easily by weighing an accurately known vol-ume of liquid. This procedure is illustrated in Example 1.14. EXAMPLE 1.14 A chemist, trying to identify the main component of a compact disc cleaning fluid, finds that 25.00 crrr' of the substance has a mass of 19.625 g at 20C. The following are the names and densities of the compounds that might be the main component:...
