- I am trying to ascertain the density of 0.9-M HCl. The book provides a density of 1.0-M HCl as 1.016g/mL. I know the Molecular Weight aka Molar Mass is 36.46g/mol I also know that the equation to calculate the density in this instand is: Density=(Molarity x Molecular Weight)/WeightI have found examples online, and one answer provided here that shows the Density of 0.9-M HCl is 0.9115g/mL. That answer was arrived at as follows:Density = (0.9M x 36.46g/mol)/36 = 32.814/36 = 0.9115g/mL My problem is that I don't understand where the 36 came from for "weight", and I need to be able to show all unit measurements for each step. So my issue has 2 parts: 1) How was the Weight value determined to be 36 (I need to see the formula)2) Where in the step-by-step process is mL in there so that after all cancellations/conversions are completed, the only remaining units are g/mL to show how 0.9115g/mL was arrived at.As part of the aspirin synthesis lab the orgo students also had to perform the following calculation to demonstrate their knowledge. Are you able to help them work this out? Saponification is a process in which soap is produced from the chemical reaction between animal fat (triglycerides) and a strong base such as KOH. An example of such balanced chemical reaction is shown here: C51H98O6 + 3KOH → C3H5(OH)3 + 3C16H31O2K (Triglyceride) (Soap) if during the saponification reaction 231.5 g of C51H98O6 is mixed with 231.5 g of KOH and 160 g of soap is produced. Calculate the theoretical yield of soap C16H31O2K and indicate who is the limiting reactant. (Provide your answer to 2 decimal places) Calculate the percent yield for this reaction (Provide your answer to 1 decimal place) *Show ALL steps and mathematical equations involved in your calculations to help the orgo students.

- Mass of Empty Beaker is 141.2g, Beaker + Water is 388.3g, mass of water is 247.1g, volume of water is 0.2471mL, calculate volume H2=Volume displaced waterhow many grams are in 5.32x10^22 molecules of CO2 -I'm not sure what to do i was wondering if you could set it up the whole equation side by side when doing the conversion factors, so i can see it laid out. (hopefully that makes sense)Automobiles are often implicated as contributors to global warming because they are a source of the greenhouse gas CO2. How many pounds of CO2 would your car release in a year if it was driven 110. miles per week? Gasoline is a complex mixture of hydrocarbons. In your calculations, assume that gasoline is octane (molecular formula C8H18) and that it is burned completely to CO2 and H2O in the engine of your car. Also assume that the car averages 27.3 miles per gallon and that the density of octane is 0.703 g cm-3.
- An industrial-scale process for making acetylene consists of the following sequence of operations: CaCO3 → CaO + CO2limestone lime carbon dioxideCaO + 3 C → CaC2 + CO calcium carbide carbon monoxideCaC2 + 2 H2O → Ca(OH)2 + C2H2 calcium acetylene hydroxide What is the percentage yield of the overall process if 2.32 metric tons C2H2 is produced from 10.0 metric tons limestone (1 metric ton 5 1000 kg)?Carbon dioxide (CO2) is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fuels is a major cause of the increased concentration of CO2 in the atmosphere. Carbon dioxide is also the end product of metabolism. Using glucose as an example of food, calculate the annual human production of CO2 in grams, assuming that each person consumes 5.0 × 10^2 grams of glucose per day. The world's population is 7.2 billion, and there are 365 days in a year.For the following problem you should describe in complete sentences the steps you would take to solve the problem and indicate what information you obtain in each step. You do not need to find a numerical answer. You might want to use dimensional analysis to show that your answer has the correct units. Each year in the spring rhododendrons should be fertilized. The recommended fertilizer is described as 10-8-6, which means 10% N, 8% P2O5 and 6% K2O by mass. How many grams of ammonium nitrate (NH4NO3) would you need to produce 1 kg of fertilizer that is 10% N? You do not need to consider the other compounds that are necessary to provide phosphorous and potassium.
- Swimming pool water is often made safe for swimming by treating with chlorine in the form of sodium hypocholrite (NaOCI) solution. If a swimming pool contains 5.62×10^5L of water, what volume of 5.00% NaOCI (by mass) solution is required to produce a sodium hypoclorite concentrarion of 3.00×10^-7 mol /L? (assuume the density of water and the NaOCI solution is 1.00g/ml). Do not give handwriting solution.In biological systems, enzymes are used to accelerate the rates of certain biological reactions. Glucoamylase is an enzyme that aids in the conversion of starch to glucose (a sugar that cells use for energy). Experiments show that 1 μg mol of glucoamylase in a 4% starch solution results in a production rate of glucose of 0.6 μg mol/(mL)(min). Determine the production rate of glucose for this system in units of lb mol/(ft3)(day). A. 0.0015 lb mol/(ft3)(day) B. 0.0315 lb mol/(ft3)(day) C. 0.0539 lb mol/(ft3)(day) D. 0.3569 lb mol/(ft3)(day)Liquid hexane CH3CH24CH3 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. What is the theoretical yield of carbon dioxide formed from the reaction of 37.9g of hexane and 102.g of oxygen gas? Be sure your answer has the correct number of significant digits in it. I keep getting this problem wrong because of the sig. digits, dont round till the end because if it is off by 0.1, it will be incorrect.
