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 does the term density and refractive index mean?
The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.
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.
What do you mean by optical density?
optical density is the amount of light
What is the effect of decreasing the incubation time on optical density?
The effect of decreasing incubation time on optical density is that optical density decreases. Incubation time and optical density have a proportional relationship.
What is optical density of diamond?
The optical density of a diamond can be found on the RI (refractive index).It is 2.417
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
Does a substance having high optical density have to have a high physical density?
It's not necessary. If a compound has high optical density, it means that it absorbs more light at the given wavelength than some reference compound. There is no simple relation between density of matter and optical density. Even more I am pretty sure you can find a lot of compounds with lower densities (of matter) but having high optical density.
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.
