What is the total volume of 70 percent ethanol from 1600ml ethanol?
If I understand you correctly, we are trying to find the volume of 70% of 1600 ml of ethanol. That said: here is how you do it:1. Change 70% into a decimal. You do this by moving the decimal point two places to the right. This would turn 70 into .702. Multiply .70 x 1600.3. The answer is: 1120mL.
When the temperature of ice is increased slightly. Does it undergo a net expansion or net contraction?
When the temperature of ice is increased slightly, it undergoes a net contraction. This is because the thermal energy causes the ice molecules to vibrate more vigorously, thereby reducing the overall structure of the ice and resulting in a decrease in volume.
How can solids liquids and gases be made to contract?
Solids, liquids, and gases can be made to contract by reducing their temperature. Cooling these substances causes their particles to move more slowly, resulting in a decrease in volume. This decrease in volume leads to contraction of the material.
How do you find the volume of 15 grams of ethanol?
Ethanol (USP grade) has a density of 0.810. From here we have to use the formula: d=m/v, where d is density, m, mass and v, volume. Solving for volume, we have v=m/d, therefore: v= 15/0.810 = 18.52 mL of ethanol are equivalent to 15g.
What is the link between percentage by volume and units of alcohol?
Percentage by volume (ABV) represents the amount of alcohol present in a beverage compared to the total volume. Units of alcohol are a measure used to quantify the amount of pure alcohol consumed. To calculate units of alcohol, you multiply the volume of the drink in ml by the ABV percentage and divide by 1000. This gives you the amount of pure alcohol in the drink, measured in units.
What is the percent volume of ethanol?
The percent volume of ethanol in a solution is the volume of ethanol divided by the total volume of the solution, multiplied by 100. It is commonly used to express the concentration of ethanol in alcoholic beverages or solutions.
Is volume conserved in a reaction between distilled water and ethanol?
Yes, volume is typically conserved in a reaction between distilled water and ethanol. The total volume of the reactants should equal the total volume of the products in a chemical reaction, assuming no gases are produced or consumed.
What is it called when materials shrink as they cool?
This phenomenon is called thermal contraction or simply contraction. When materials cool, the decrease in temperature causes the atoms and molecules to slow down, leading to a decrease in volume and a contraction of the material.
What change a materials volume by expansion and compression?
Heating a material causes it to expand, increasing its volume, while cooling a material causes it to contract, decreasing its volume. The expansion and contraction of materials are due to changes in the intermolecular spacing as the temperature changes.
The Frank-Starling law of the heart describes the relationship between?
stroke volume, end-diastolic volume, and contraction strength
What s the volume of 495g or ethanol?
The volume of 495g of ethanol can be calculated by dividing the mass by the density of ethanol. The density of ethanol is approximately 0.789 g/ml at room temperature. Therefore, the volume of 495g of ethanol would be 495g / 0.789 g/ml ≈ 627 ml.
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.
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 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.
What is the volume of 75.0g of ethanol?
The volume of 75.0g of ethanol can be calculated using the density of ethanol, which is about 0.789 g/mL at 20°C. By dividing the mass by the density, we find that the volume would be approximately 95.1 mL.
Increasing the amount of money in circulation causes?
Contraction in the volume of available money or creditthat results in a general decline in prices. Deflation, is the answer.
What is the total volume of 70 percent ethanol from 1600ml ethanol?
