An organic liquid is a mixture of methyl alcohol (CH3OH) and ethyl alcohol (C2H5OH). A 0.220-g sample of the liquid is burned in an excess of O2(g) and yields 0.364 g CO2(g) (carbon dioxide).

Set up two algebraic equations, one expressing the mass of carbon dioxide produced in terms of each reagent and the other expressing the mass of sample burned in terms of each reagent.What is the mass of methyl alcohol (CH3OH) in the sample?

Express your answer numerically in grams.

    You need to measure out 2.50 grams of ethyl alcohol. Because it is a liquid, you decide that it would be easier to get that mass value by measuring the sample by volume. If ethyl alcohol has a density of 0.789 g/mL, what volume of the liquid would you need? Show your calculations. 2. Should density be considered a value that is exact by definition? Explain your answer. 3. You made some preliminary calculations for an object that you want...
