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.
Does water have a greater mass than lead?
water has less density than lead. Mass depends on its volume
What does volume and mass have to do with flotationn?
The density of an object is its mass divided by its volume. If that is less than the density of water, it will float; if greater it will sink
What happens when a pressure greater than atmospheric pressure is applied on pure water?
It is compressed and occupies a smaller volume.
How does one prepare 30 percent ethanol?
30 ml of ethanol to 70ml of distilled water.
Which has a greater volume 1000g of water or 1000g of denatured ethanol?
1000g of water has a greater volume than 1000g of denatured ethanol because water is denser than ethanol. This means that water occupies less space per gram compared to ethanol.
Does water with a greater volume cool faster than water with a less volume?
No, water with a greater volume will cool slower than water with a lower volume because it takes more energy to heat or cool a larger volume of water. The larger volume of water will retain heat longer than the smaller volume.
Which takes up a greater volume - 1000g of water or 1000g of alcohol?
Its is the same.
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.
What is the percent by volume of 45 mL of ethanol dissolved in 125 of water?
To calculate the percent by volume, add the volumes of ethanol and water together (45 mL + 125 mL = 170 mL). Then determine the percentage of ethanol in the total volume by dividing the volume of ethanol by the total volume and multiplying by 100 (45 mL / 170 mL * 100 ≈ 26.47%). Therefore, 45 mL of ethanol dissolved in 125 mL of water represents approximately a 26.47% ethanol solution by volume.
What causes volume contraction between ethanol and water?
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
The total volume of the solution is 48 mL + 144 mL = 192 mL. The percent by volume of ethanol is calculated as (volume of ethanol / total volume of solution) * 100%. Plugging in the values, we get (48 mL / 192 mL) * 100% = 25%. So, the solution contains 25% ethanol by volume.
Will the volume of lead be greater or less than one gram of water?
The volume of lead will be greater than one gram of water. The density?æof lead is about 11 times more than that of water.?æ
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.
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.
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.
Which liquid expands more Ethanol or Water?
Ethanol expands more than water when heated because it has a higher coefficient of thermal expansion. This means that ethanol will increase in volume more than water when heated to the same temperature.
