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
What is the weight of ethanol that fills exactly 200.0 mL container?
The density of ethanol is 0.789 g/mL
What is the density of ethanol at 78 degree Celsius?
736.7 kg/m3
What are the mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume-The density of water is 1.00g per mL and that of ethanol is 0.789 grams per mL?
The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.
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 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.
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
Density of ethanol?
0.790 at 20C
Which has more density vegetable oil or ethanol?
The vegetable oil is more dense than ethanol. Vegetable has a density of around 0.9 g/cm3, which varies very slightly depending on the oil. The density of ethanol is 0.789 g/cm3
If ethanol has a density of 789 g then what is the mass of 225 g of ethanol?
225 g
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.
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.
Do water acid mercury and alcohol have the same density?
No. They have very different densities. There are several types of alcohol, but for these purposes, we will use ethanol, the alcohol found in drinks. Density of water ≈ 1g/cm3 Density of ethanol = 0.789g/cm3 Density of mercury = 13.5 g/cm3 So water is about 20% denser than alcohol, and mercury is more than 13 times denser than water. Note that the density given from ethanol is for pure ethanol. Most alcoholic beverages are mixtures, with densities between those of water and pure ethanol.
What is the weight of ethanol that fills exactly 200.0 mL container?
The density of ethanol is 0.789 g/mL
What is the density of ethanol at 78 degree Celsius?
736.7 kg/m3
Why is 70 percent ethanol used in rna extraction?
The density of 70% ethanol allows RNA settlement or say sedimentation in the vial.
