How many kilowatts does the 4.0 liter jeep wrangler motor have?
3.95 Kilowatts
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
Why liter of water is heavier than liter of ethanol?
The density of water is greater than the density of ethanol. This is partly a result of how tightly packed the molecules of the substance are.
How many moles of ethanol per liter?
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
How do you dilute from ethanol 96 percent to 70 percent?
There's a dilutionfactor of 70/96=0.729, when you make 1 liter, you have to use 729 milliliters of ethanol, then you to add water till 1 liter total.
How many cm3 of ethanol per liter does wine contain?
Ordinary (non-fortified) wine will contain around 130 cm^3 of ethanol.
How many grams of ethanol are in a 0.7 liter bottle of wine?
you need to state the % alcohol of the wine (%vol/vol). find out ethanol's density and then you can calculate the weight ethanol per litre, /1000,x700 per 700ml.
The approximation energy content of a liter of petrol?
Standard petrol has an energy content of approx. 9.67kWh/liter (34.8MJ/liter)
What amount of ethanol is needed to produce the equilavent a liter of petrol energy wise?
Ethanol contains less than half the energy per litre as is contained in an equal amount of petrol (Petrol= 77.3 MJ/kg, Ethanol = 29.7 MJ/kg.) This does nor account for the higher production energy costs associated with production of fuel grade ethanol from food grade crops like wheat or corn. You would have to burn more than twice the volume of fuel in an ethanol powered car.
How do you convert ethanol in liters to tons?
establish the weight of one liter of ethanol, establish long tonnes vs. short tons... 2200lbs vs. 2000lbs, ....roughly 1400 liters = 1 ton
How much CO2 does a car running on ethanol fuel produce?
Assuming the fuel is 100% ethanol the reaction is: C2H5OH +3O2 --> 2CO2+3H20 or 1 mole of ethanol (46 g) creates 2 moles (44 x 2=88) of carbon dioxide The density of ethanol is 0.78 g/cm3 or .78 kg/L So the amount of carbon dioxide created by a car fueled by ethanol is about 1.56 kg/liter used. This excludes CO2 from ethanol manufacture.
What is the mass of ethanol dissolved in one liter of a 6.8 percent ethanol solution?
1 liter exactly equals 1000 cubic centimeters (abbreviated cc, or cm3). A 6.8 percent solution means that of those 1000 cc's, 68cc's are of ethanol ((6.8/100) x 1000) Assuming pure ethanol, which it most likely is for a school problem, Wikipedia states that the density is: 0.789g/cm3 (0.789g/cc) so, 68 x 0.789 = 53.652 grams.
