Ethanol/Formula
ethanol, also called ethyl alcohol, grain alcohol, or alcohol, a member of a class of organic compounds that are given the general name alcohols; its molecular formula is C2H5OH.
How do you calculate osmotic pressure the concentration of solute is expressed in?
In calculating osmotic pressure the concentration of solute is expressed in molarity.
What is mole fraction of water?
The molecular weight of water is considered to be 18.0153 grams per mole. Example 2: Calculate the mole fraction of acetone that is present in a solution which consists of 2 moles of benzene, 3 moles of carbon tetrachloride, and 5 moles acetone.
Which of the following 0.1 M aqueous solution will exert highest osmotic pressure?
Answer: Hence, Al2(SO4)3 will exert the highest osmotic pressure for the same concentration.
Which aqueous solution has minimum freezing point?
The aqueous solution of 0.01M NaCl has a minimum freezing point.
What is the formula mass of ethanol c2h5oh?
46.07 g/mol
Ethanol/Molar mass
Is ethyl alcohol soluble in water?
Ethanol is soluble in water primarily because of the presence of -OH group that allows or enables it to form hydrogen bonds with water molecules. In other words, ethanol is soluble in water because it is a polar solvent.
How much ethyl alcohol must be added to 1.0 L of water so that solution will not freeze at 4 F?
(a) 7.5 mol – Is the correct answer to above question.
The molality of a solution of ethyl alcohol in water is 1.54 mol/kg. How many grams of alcohol is dissolved in 2.50 kg water? If 1L of ethyl alcohol is mixed with 1L of water, how many kilograms of solution result and litres result? Together the mass would be 1.9kg.
What is the molar mass of a mixture of alcohol and water?
The molar mass of H2O is 18.015 g/mol. Converting that to kilograms you get .018015 kg/mol. A mixture of alcohol and water contains 54\% water by mass. What is the mole fraction of alcohol in this solution?
How do you calculate the molality of NaCl solution?
Assume we want to dissolve 70.128 grams of salt in 1.5 kg of water. so moles NaCl = 70.128 g / (58.44 g/mol) = 1.2 mol. Plug moles value and the mass of the solvent into the molality formula. Divide 1.2 mol by 1.5 kg, and you’ll find out that the molality of the NaCl solution is 0.8 molal (in standard molality units: 0.8 mol/kg).
What is the molality of a solution?
As is clear from its name, molality involves moles. Boy, does it! The molality of a solution is calculated by taking the moles of solute and dividing by the kilograms of solvent.
