What is the density of 95 ethanol?
According to the CRC Handbook, 70th edition, the density of 94% ethanol is 0.8070 g/ml and the density of 96% ethanol is 0.8013 g/ml. We can interpolate to find that the 95% ethanol should be 0.8042 g/ml.
Is hexane more dense than ethanol?
No, hexane is less dense than ethanol- hexane has a density of 0.6548g/mL and ethanol has a density of 0.789g/mL, so hexane will float on top of ethanol.
How many molecules of ethanol are contained in a 19.6 mL sample 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).
What is the mass in mg of thanol of 5.1 1020 molecules of ethanol?
mass in mg. of ethanol of 5*1020 molecules of ethanol
What is the volume of 85.5g of ethanol?
108.365mL or 108.365 cm3, this is based on the density of the ethanol which is 0.789g/mL.
What volume of ethanol has a mass of 15.5 grams?
15.5 gram ethanol x 1 mL/0.789 (density) = 19.65 mL the density of ethanol is 0.789g/mL
If a sample of ethanol has a volume of 60.0 ml what is the mass?
5
Mass of 25.0 milliliter ethanol?
At STP, pure ethanol has density 0.789g/mL. 25 mL will have mass25 (mL) * 0.789 (g/mL)=19.725 g. Round this to 19.7g for three significant figures.
How do you find the total volume of ethanol if the total mass is 60.345?
Divide by the density of ethanol.Assuming that it is a total mass of 60.354 grams, and the density of ethanol is 0.789 grams per cm3 (or grams per mL), then the volume of that much ethanol is:60.354 grams ÷ 0.789 grams/mL = 76.494 mL
What is the mass in grams of 147 mL of ethanol?
The density of ethanol at 20 deg C and normal presure is 0.789 g/mL.So the mass of 147 mL is 147*0.789 = 116.0 grams (approx).The density of ethanol at 20 deg C and normal presure is 0.789 g/mL.So the mass of 147 mL is 147*0.789 = 116.0 grams (approx).The density of ethanol at 20 deg C and normal presure is 0.789 g/mL.So the mass of 147 mL is 147*0.789 = 116.0 grams (approx).The density of ethanol at 20 deg C and normal presure is 0.789 g/mL.So the mass of 147 mL is 147*0.789 = 116.0 grams (approx).
What is the link between percentage by volume and units of alcohol?
An UK unit of alcohol has 10 mL (8 g) ethanol. Calculate the mass or the volume of ethanol in your drinks.
What has the greatest mass 3.48 milliliter of mercury or 60.0 milliliter of alcohol?
Density mercury ≈ 5.43 g/ml. Density alcohol (ethanol) ≈ 0.789 g/ml. mass = density x volume ⇒ mass mercury ≈ 5.43 g/ml x 3.48 ml ≈ 18.90 g ⇒ mass alcohol ≈ 0.789 g/ml x 60.0 ml ≈ 47.34 g ⇒ 60.0 ml of alcohol has more mass than 3.48 ml of mercury.
How many grams of alcohol are in 150 mL?
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
What mass of ethyl alcohol would occupy a volume of 7.5 milliliters?
The mass of 7,5 mL pure ethanol at 20 0C is 5,920 875 g.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?
Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
What is the weight of ethanol that fills exactly 200.0 mL container?
The density of ethanol is 0.789 g/mL
How does one prepare 500ml of 70 percent ethanol?
150 ml ethanol to 350 ml distilled water
