When 1.51 g1.51 g of quinine is dissolved in 25.0 g25.0 g of cyclohexane, the freezing point of the solution is lowered by 3.88 C.3.88 C. Majer, V.; Svoboda, V., Data, 1996, 41, 365-372. 0000047096 00000 n
mass = d v vcfmcf, where mcf is the conversion factor to convert from gram to kilogram (table near the end of this page) and vcf is the conversion factor to convert from milliliter to cubic meters. Gaw, W.J. Soc., 1942, 64, 2482-2485. AIChE Symp. (Moscow), 1965, 38, 378-383. Again - hit calculate first so the URL is updated with your most recent changes. Chem. No packages or subscriptions, pay only for the time you need. 2. some cyclohexane evaporated after the solute was added. Prikl. the molar mass of a chemical compound based on the compound's empirical formula. Now here we have to find the molar mass of Cyclohexane (C6H12). To transform the mass from pounds to kilograms we should multiply the mass in pounds by 0.45359237. <<08A6CCB0ADB66B4A8F8BC681AF617041>]>>
