How many molecules contains 0.5L of c2h6o and how many hydrogen atoms?
The answer is 51,568.10 ex.23 molecules and 309,408.10 ex. 23 hydrogen atoms.
Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.
how many molecules of ethanol are there in 1 liter of ethanol (density: 800 gr/l)?
Mass of 1 liter ethanol = 800 gram Molar Mass of ethanol = 46.07 gram/mol Therefore, Number of moles in 1 liter ethanol = 800/46.07 = 17.365 mol Number of molecules in 1 mol of ethanol = 6.023 × 10²³ molecules Therefore, Number of molecules in 1 liter of ethanol = 17.365 × 6.023 × 10²³ molecules = 104.599 × 10²³ molecules = 1.05 × 10²⁵ molecules
Which has the lower freezing point oxygen or ethanol and why?
Oxygen has a lower freezing point than ethanol. This is because the intermolecular forces in oxygen molecules are weaker than in ethanol molecules, allowing oxygen to freeze at a lower temperature.
How many calories are in ethanol?
Ethanol contains about 7 calories per gram.
How many molecules of ethanol can be obtained from one molecule of sugar?
From one molecule of glucose (sugar) you can obtain two molecules of ethanol. Glucose's chemical composition is C6H12O6 Carbon dioxide (Co2) is lost in the fermentation process so we are left with 2C2H5OH or two ethanol molecules! Hope it helps!
Why does methane dissolve in ethanol?
ethanol contains both a polar and a nonpolar part. The hydroxyl (OH) part is polar and the thane is non polar. so methane which is nonpolar can be dissolved by the ethane as the saying goes ''like dissolves like''.
Why ethanol called universal solvent?
Ethanol is a universal solvent as it contains both polar nature (OH) ion and the ethyl group which is a non polar substance. As a result it means that both polar nature molecules and non polar nature molecules can bond with ethanol which can as well form hydrogen bonding amongst substances.
Why ethanol is insoluble in oil?
Ethanol is a polar molecule, while oil is nonpolar. This difference in polarity results in ethanol being insoluble in oil because the interactions between the molecules of each substance are not favorable. Ethanol molecules are more attracted to each other than to the oil molecules, leading to poor solubility.
Why is ethanol solubile in water but propane is not?
Ethanol is soluble in water due to its ability to form hydrogen bonds with water molecules. Ethanol contains a hydroxyl (-OH) group that can participate in hydrogen bonding with water molecules, allowing it to dissolve in water. In contrast, propane is a nonpolar molecule with only weak van der Waals forces between its molecules, which are not strong enough to overcome the strong hydrogen bonding in water, making it insoluble in water.
When 50 mL of ethanol is mixed with 50 mL of water a solution forms The volume of the final solution is less than 100 mL Propose an explanation for this phenomenon?
When ethanol and water are mixed, they form a solution with a volume less than the sum of the individual volumes due to the molecules of ethanol and water packing closely together in the solution. This phenomenon is known as partial miscibility, where the molecules of ethanol and water interact with each other in a way that reduces the total volume of the solution.
What is the mass in mg of thanol of 5.1 1020 molecules of ethanol?
To calculate the mass of 5.1 x 10^20 molecules of ethanol, first determine the molar mass of ethanol (46.07 g/mol). Then convert this to mg/mol (46,070 mg/mol). Finally, multiply the molar mass by the number of molecules to find the total mass in mg (approximately 2.35 x 10^25 mg).
