A student determines the molar mass of a liquid unknown by the method used in thisexperiment. She found that the equilibrium temperature of a mixture of ice and water was1.0°C on her thermometer. When she added 12.3 g of her unknown sample to the mixture, thetemperature, after thorough stirring, fell to -4.0°C. She then poured off the solution through ascreen into a beaker. The mass of the solution was 93.4 g. Kf = 1.86°C/m What was the molality of the unknown solution? ______________ m How much unknown liquid was in the decanted solution? ______________ gHow much water was in the decanted solution? ______________ gWhat did she find to be the molar mass of the unknown liquid, assuming she made thecalculation properly?______________ g

Natural gas is very abundant in many Middle Eastern oilfields. However, the costs of shipping the gas to markets inother parts of the world are high because it is necessary toliquefy the gas, which is mainly methane and has a boilingpoint at atmospheric pressure of -164 °C. One possiblestrategy is to oxidize the methane to methanol, CH3OH,which has a boiling point of 65 °C and can therefore beshipped more readily. Suppose that 10.7 * 109 ft3 of methaneat atmospheric pressure and 25 °C is oxidized to methanol.(a) What volume of methanol is formed if the densityof CH3OH is 0.791 g>mL? (b) Write balanced chemicalequations for the oxidations of methane and methanol toCO21g2 and H2O1l2. Calculate the total enthalpy changefor complete combustion of the 10.7 * 109 ft3 of methanejust described and for complete combustion of the equivalentamount of methanol, as calculated in part (a).(c) Methane, when liquefied, has a density of 0.466 g>mL;the density of methanol at 25 °C is 0.791…

Methanol is known to be the simplest alcohol, and is used as an antifreeze agent, a solvent, a fuel anda denaturant for ethyl alcohol. It is also known as “wood spirit”, as it is obtained from the pyrolysis ofwood. Methanol burns in air to produce CO2(g) and H2O(l). The chemical reaction is: 2CH3OH (ℓ)+ 3O2 (g) à 2CO2 (g) + 4H2O (ℓ)Calculate the enthalpy change for the reaction using the standard enthalpies of formation are found onthe chart provided.

A standard air conditioner involves a refrigerant that is typicallynow a fluorinated hydrocarbon, such as CH2F2. Anair-conditioner refrigerant has the property that it readilyvaporizes at atmospheric pressure and is easily compressedto its liquid phase under increased pressure. The operationof an air conditioner can be thought of as a closedsystem made up of the refrigerant going through the twostages shown here (the air circulation is not shown in thisdiagram). During expansion, the liquid refrigerant is released into anexpansion chamber at low pressure, where it vaporizes. Thevapor then undergoes compression at high pressure backto its liquid phase in a compression chamber. (a) Whatis the sign of q for the expansion? (b) What is the sign ofq for the compression? (c) In a central air-conditioningsystem, one chamber is inside the home and the other isoutside. Which chamber is where, and why?
