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
AnswerThe density of ethanol is 0.789 g/cm³ , and there are 1000 cm3 in a liter, so 1 liter weighs 0.789 kilograms.Density = mass/volume, So mass=density*volume.So, weight of 1L ethanol = 0.789*1 => 0.789KG
Assuming 12% alcohol content in wine, there would be 84 grams of ethanol in a 0.7 liter bottle of wine. This is calculated by multiplying the volume of wine by the alcohol content percentage and the density of ethanol.
The density of ethanol is 0.789 g/mL. So 19.6 mL of ethanol weighs 0.789 g/mL * 19.6 mL = 15.464 g. The molar mass of ethanol is 2*12.011 + 6*1.008 + 15.999 = 46.069 g/mol. So, in 15.464 grams, there are 15.464 g / 46.069 g/mol = 0.33567 moles In one mole, there are 6.022*1023 molecules, so we have: 0.33567 moles * 6.022*1023 molecules/mole= 2.0214*1023 molecules. Using correct significant digits, that gives: 2.02*1023 molecules (or particles).
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!
Ordinary (non-fortified) wine will contain around 130 cm^3 of ethanol.
Depends on the density of the yoghurt.
The answer is 780,65 carbon atoms.
Grams is weight. Liter is volume. The answer would depend on the density of the substance.
Not comparable - a liter is a unit of volume, a kilogram is a unit of mass. For specific substances, if you know the density, mass = volume times density.
This fuel has density approx 0.75 kg/liter, which is 1.65 lb/liter
The answer is 51,568.10 ex.23 molecules and 309,408.10 ex. 23 hydrogen atoms.
Sesame Oil has a Density of 0.916-0.920 Kg/Liter
