- A mixture of methanol and water contains 60.0% water by mass. Assuming volume additivity: If the actual specific gravity of the mixture is 0.9345: How many liters is required to provide 150 mol of methanol?kindly help me with this problem solve as neatly as possible and show completesolution. Round your final answer to 4 decimal places and box / highlight all final answers. all values must include proper units with properconversion if needed in your solution. Please follow the format Given,Required,Solution thank you! 1. The following data were taken in measuring the molecular weight of a certain gas by theRegnault’s Method: o Wt of evacuated bulb : 32.5050 go Wt of bulb+gas : 33.5417 go Wt of bulb+water : 385.31 go Temperature : 25 OCo P : 760 mm HgFind the Molecular Weight of the gas. What could have been this gas?A core sample is saturated with an oil (?o = 35oAPI), gas and water. The initial weight of the sample is 224.14 g. After the gas is displaced by water (?w = 1 g/cm3 ), the weight is increased to 225.90 g. The sample is the placed in a Soxhlet distillation apparatus, and 4.4 cm3 water is extracted. After drying the core sample, the weight is now 209.75 g. The sample bulk volume, 95 cm3 is measured in a mercury pycnometer. Find the porosity, water saturation, oil saturation, gas saturation and lithology of the core sample.
- 5.86 A student mixes 88.6 g of water at 74.3°C with 57.9 gof water at 24.8°C in an insulated flask. What is the finaltemperature of the combined water?A company has just patented a new synthetic alcohol for alcohol beverages. You analyse asample of the new product by placing a small volume of it in a round-bottomed flask with avolume of 612.0 mL and an evacuated mass of 131.918 g. You submerge the flask in a waterbath at 100°C and allow the volatile liquid to vaporize. You then cap the flask and remove itfrom the water bath. You weight it and determine the mass of the vapour in the flask to be0.9198 g. what is the molar mass of the volatile liquid, and what does it mean with regard tothe new product? (Assume the pressure is 1 atm)A mass of KHP is measured at 0.3051g and contains ______ moles. Group of answer choices
- When concentrated nitric is sold, the label contains no mention of the molarity of the acid. Instead, the label normally lists the concentration of nitric acid as a wt/wt percent and gives the specific gravity of the solution. If the solution is 68.0 (wt/wt %) and nitric acid and has a specific gravity of 1.41 kg/L, calculate the molarity of 68.0 % concentrated nitric acid. FW HNO3=63.01g/molThe mass of a beaker is 5.333g. After 5.00mL of a concentrated hydrochloric acid solution is pipetted into the beaker, the combined mass of the beaker and the hydrochloric acid sample is 11.229g. From the data, what is the measured density of the hydrochloric acid solution?The ethyl alcohol content of beers produced is reported as ABV or alcohol by volume (vol/vol) If the density of ethyl alcohol at room temperature is 0.7893 grams/mL, what is the percent of ethyl alcohol in 4.50% beer expressed as percent (wt/vol)
- When 25 g of ethanol (MW 46.07 g/mol) is mixed with 25 g of water (MW 18.02 g/mol) at 25 C, the total volume of the ethanol/water solution is 50 mL. Given that the partial molar volume of water in the solution is 17.4 mL / m ol, what is the partial molar volume of the ethanol?Produce Water mass “X” is known to be a mixture of water masses “1”, “2”, and “3”. Using the data plotted below, calculate the composition of “X” (i.e. determine the fraction from each of the 3 water masses that makes up water mass X). Watermass#1– SF6 =25 S=33.5 Watermass#2– SF6 =75 S=32 Watermass#3– SF6 =50 S=36.5 Water mass X – SF6 =60 S= 34The atmosphere is a highly complex gaseous mixture that sustains life on Earth. Approximately 99% of the air is composed of nitrogen (N2) and oxygen (O2). The remaining 1% is made up of a variety of other gases, including carbon monoxide (CO), hydrogen (H2), and ammonia (NH3), among many others. Because most of the gases that comprise the atmosphere are present at very low levels (<0.002%), their quantities are often expressed in parts per million (ppm) or parts per billion (ppb) rather than as a percent. Ozone (O3) is found in the troposphere at 2.5×10−6%. Convert this value to parts per million. [O3]= _______ ppm The atmosphere contains 2.9×10−7%2.9×10−7% nitrogen dioxide (NO2). Convert this value to parts per billion. [NO2]= _______ ppb Atmospheric methane (CH4) is present at 1983 ppb. Convert this value to a percentage. [CH4]= _______ %
