These organic solvents are used to clean compact discs:(a) If a 15.00-mL sample of CD cleaner weighs 11.775 g at 20C, which solvent is most likely to be present?(b) The chemist analyzing the cleaner calibrates her equipment and finds that the pipet is accurate to 0.02 mL, and the balance is accurate to 0.003 g. Is this equipment precise enough to dis-tinguish between ethanol and isopropanol?

Could someone check this for me, please? I am unsure which part, if any, is being done correctly. The water weights are as they are on the page (first # in qcold and first # in qhot).
A 0.1 g amine-containing compound is dissolved in water then diluted to 100 mL. You subject it to spectroscopic analysis, in order to get the concentration of amine in this compound. Next, you get 1 mL of the previously diluted sample then dilute it again to 250 mL for measurement. Then, you fill 3/4 of a 1-cm cuvette with this diluted sample, and you run an analysis using an AAS. The recorded absorbance is 0.545 at 410 nm. What is the molecular weight of the compound? (The molar absorptivity is 1.23 x 104 cm-1 mol-1 L.)
Please could someone help me with this question? I need it to be set out like the second image, but for CaCl2 and not MgCl2. Many thanks
What is the percent composition of cyclohexane and toluene using the calculations in the picture? Toluene should be peaks A and B with integrations of 0.21 and 0.13 (unsure if you need to use them both) and cyclohexane is peak C with an integration of 1.00.
is the A:B ratio just a place holder for the unknown compound can you use other variables in place of "A and B" also would H2O work as another formula instead of Na2O

A mixture containing only Al2O3 (FM 101.96) and Fe2O3 (FM 159.69) weighs 2.019 g. When heated under a stream of H2, the Al2O3 is unchanged, but the Fe2O3 is converted to metallic Fe plus H2O(g). If the residue weighs 1.774 g, what is the weight percent of Al2O3 in the original mixture? (Do not include % symbol in your answer.)
