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.

What is the volume of 85.5g of ethanol?

To find the volume of 85.5g of ethanol, you need to know the density of ethanol. The density of ethanol is approximately 0.789 g/mL at room temperature. You can divide the mass of ethanol (85.5g) by its density (0.789 g/mL) to find the volume in milliliters.


Will ice sink or float in ethanol?

Ice will float in ethanol because ice is less dense than ethanol. The density of ice is about 0.92 g/cm3, while the density of ethanol is about 0.79 g/cm3. This difference in density causes ice to float in ethanol.


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.


Why 95 percent ethanol is used in laboratory?

95% ethanol is commonly used in laboratories because it is an effective solvent for a wide range of chemicals and biological substances. It also has antimicrobial properties, making it useful for disinfecting surfaces and equipment. Additionally, 95% ethanol is less prone to evaporation compared to absolute ethanol, providing a more stable solution for various applications.


How do you prepare 95 percent ethanol from absolute ethanol?

To prepare 95% ethanol from absolute ethanol, you would need to dilute the absolute ethanol with a calculated amount of distilled water. Since absolute ethanol is 100% pure, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (100%), V1 is the volume of absolute ethanol, C2 is the desired concentration (95%), and V2 is the final volume of the diluted solution. By rearranging the formula and solving for V1, you can determine the volume of absolute ethanol needed to achieve a 95% ethanol solution when mixed with water.

How do you calculate the density of an ethanol-water mixture?

To calculate the density of an ethanol-water mixture, you would use the formula: Density (mass of ethanol mass of water) / (volume of ethanol volume of water) You would need to know the masses and volumes of both ethanol and water in the mixture. Then, you can plug these values into the formula to find the density of the mixture.

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 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
