SHOW UNIT CONVERSION PROCESS IN SPACE PROVIDED BELOW EACH QUESTION FOR FULL CREDIT. 1. Assume your hybrid car gets 38.0 miles per gallon (mpg) and the current price per gallon of regular, unleaded gasoline is $2.52. The car’s gas tank holds 11.5 gallons. a. How far (in km) can the car travel on a tank of gas?Capacity of tank = 11.5 gallons1 gallon can be used to travel 38 miles11.5 gallons = 11.5 * 38 = 437 miles b. What will be the cost of gasoline for a 160-mile trip? Amount of gasoline required for 160-mile trip:1 gallon covers 38 miles, therefore160-mile trip would require 160/38 = 4.21 gallonsCost of 1 gallon = 2.52 * 4.21 = $10.61 c. How far (in miles and km) can the car travel on $10.00 worth of gas? Gallons in $10 worth of gas = 10/2.52 = 3.97 gallons1 gallon covers 38 miles3.97 gallons…

Sugar Cane Solution Evaporation. Evaporator is used to thicken sugar cane solution. The feed rate is 10,000 kg / day, wherein the solution contains 25% (w / w) solid sugar. The result of thickening is that of a 65% (w / w) solution of solid sugar. Calculate the weight of the solution produced and the amount of air removed. (a) The weight of the solution produced = Answerkg (b) The amount of air removed = Answerkg
In an experiment to calibrate a 50 ml burette at 30 ⁰C, a student calculated the volume corrections for a series of volumes delivered by the burette and recorded the following data 1. Plot a graph of volume corrections against apparent volumes and briefly describe the nature of the graph 2. If a student used this burette to measure 45ml of water at 30⁰C, what will be the true volume of water delivered at this temperature
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of carbon tetrachloride, diethylamine, methyl acetate, tetrahydrofuran, and acetone. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information:

Molly inflates a beach ball to a volume of 8 liters in her air-conditioned house where the temperature is 19 °C. Later that day, Molly takes the beach ball to the beach with some friends. The temperature at the beach was 33 °C, and the air pressure at the beach is the same as it was at the house. What will happen to Molly′s beach ball when she is at the beach? First, solve the problem EXACTLY like the example attached. Apply to the significant figure rule to your final answer. The final answer should have one significant figure. On taking the beach ball to the beach where the temperature is high, the ball will expand. Charles Law can be used to verify this because the pressure inside the beach ball is constant. V1=8.0 L, T1=19 °C, T2= 33 °C. For our Celsius numbers, we must convert them to Kelvin. The temperature can be converted from Celsius to Kelvin just by adding the number 273 to it. T1= (19 °C+273) K, T1= 292 K. T2= (33 °C+273) =, T2=306 K. According to Charles Law, V2/T2=V1/T1.…

You are on the management team of a company that is considering purchasing a tanker truck. The truck you want has a volume of 26,000 liters and an empty mass/weight of 15,500 kg. However, the route you wish to travel has a bridge with a weight limit of 25 tons. If you purchase the truck and fill it to capacity with a liquid whose density is 0.80kg/L, what will the mass of the truck be?
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…
