- What is the Molecular weight of a certain volatile liquid which is placed in 225 g flask which has total capacity volume of 252.17 mL. After the liquid was heated to 96.7 oC the gass volatilized and the weight of the flask measure 227.33g.

- 10.5mL (mw 106) of benzaldehyde and 2.9g(3.63mL, mw 40) of acetone react with 5g of NaOH and 25mL of Ethanol to form 6.7g of Dibenzalacetone. What is the theoretical, actual and percent yield?In a metered-dose inhaler (MDI), such as those used for asthma medication, medicine isdelivered by a compressed-gas propellant. (The device is similar in concept to a can of spraypaint.) When the inhaler is activated, a fixed amount of the medicine suspended in thepropellant is expelled from the mouthpiece and inhaled. In the past, chlorofluorocarbons(CFCs) were used as propellants; however, because of their reactivity with the Earth's ozonelayer, they have been replaced by hydrofluorocarbons (HFCs), which do not react withozone. Now HFC use is also being reduced due to their high global warming potential. In one brand of inhalers, the original CFC propellant was replaced by HFC 227ea (C3HF7,heptafluoropropane). The volume of the inhaler propellant reservoir is 1.00×102 mL, and thepropellant is charged into the reservoir to a gauge pressure of 4.443 atm at 23°C. An onlinesearch for properties of HFC 227ea yields the information that the critical temperature andpressure of the substance…Hot mix asphalt (HMA) is commonly used in the construction of roadways in the United States at a rateestimated to be 500,000,000 tons/year. A typical upper layer (there may be as many as 5 layers ofdifferent thicknesses and compositions) of a high-volume highway is composed of crushed stone (alsoknown as crushed aggregate) and asphalt binder and is approximately 1.25 inches thick. The stone,which has a specific gravity of about 2.7, is mixed with asphalt binder (SG = 1.03) to form the HMAwith a composition of approximately 95 wt% aggregate and 5% asphalt. What is the volume ft3 of asphalt binder and weight (tons) of HMA required for the top layer of a 15-mile segment of interstatehighway with 5 lanes, each of which has a width of 12 ft?
- A given soil sample is subjected for proximate analysis - specifically moisture content and analysis of inorganic matter (or ash) content. A cleaned and tared crucible is weighed in an analytical balance and found to be 4.5015 grams . The soil sample is weighed-in and the crucible, together with the plant sample, measured a total of 6.2525 grams. The set-up is then placed in an oven and dried to 105 degrees Celsius for at least two hours. The setup is cooled to room temperature in a dessicator and then measured to a constant weight of 5.9775 grams. Afterwards, the setup is placed inside the muffle furnace and ignited to 720 degrees Celsius for at least an hour. The set-up is cooled to room temperature again inside the dessicator and then measured to the constant weight of 4.9375 grams. (A) What is the percent moisture in the plant sample? Write the answer in THREE SIGNIFICANT FIGURES. (B) What is the percent volatile (organic) matter in the plant sample? Express answer in THREE…What could be the assumption when the MW of the sample does not match calculated molecualr weight from ∆Tb = mKb despite carefull data processing?

- Polycarbonate, PC, is used for aircraft canopies. A batch of this polymer was found to fail prematurely when impacted by a 4 pound bird during qualification studies. You suspect that the problem is due to a molecular weight difference for this particular batch of polymer compared to previous batches. You decide to perform dilute solution viscosity studies to determine the Mol.wt. Assume density is 1.2g/cm3 What solvent would you use? Justify your answer Please answer very soon will give rating surelyVarious parameters in a gas absorption experiment are as follows; Water flow rate =5 L/min, Air flow rate=25 L/min, CO2 flow rate=6 L/min. Then, to find the amount of CO2 absorbed into the water 1 hour after the system is started and stabilized, 50 mL samples are taken from the inlet and outlet of the tank and titrated with 0.01M NaOH. 100mL samples are taken from the tower entrance and exit and sent to the hemp apparatus. The consumptions measured with the help of the Hemp apparatus are 2.1 mL (inlet) and 1.9 mL (output), respectively. According to this, find the amount of CO2 absorbed by titration? (Note: The relative error in the experiment is 10.)If 35,000 kg of whole milk containing 4% fat is to be separated in a 6-hour period into skim milk with 0.45% fat and cream with 45% fat, what are the mass flow rates of the two output streams from a continuous centrifuge which accomplishes this separation? (Ans; Cream=464.8335kg/h, Skim milk= 5368.4998kg/h)
