You take 1 mol = 46 gram of pure alcohol (or equivalent 46 * [100 / masspercentage] of diluted) and add it up with water while stirring to make it 1 Litre.
[Roughly you'd have to take 60 mL 96% ethanol (this is commercially available, don't use denaturated spirit!) and fill up to 1 L.]
To prepare 1M ethanol solution, you would need to mix 46.07g of ethanol (C2H5OH) with enough water to make 1 liter of solution. Weigh out the appropriate amount of ethanol, add it to a volumetric flask, and then add water while mixing until the final volume reaches 1 liter.

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 prepare 0.2 milli molar DPPH solution in ethanol?
To prepare a 0.2 millimolar (mM) DPPH solution in ethanol, you need to dissolve 0.2 millimoles of DPPH in a final volume of 1 liter of ethanol. First, calculate the molecular weight of DPPH (usually around 394.33 g/mol) to determine the mass needed to dissolve in ethanol. Then add this mass of DPPH to ethanol and make up the volume to 1 liter.
How do you prepare 80 percent ethanol?
Oh, dude, preparing 80% ethanol is like making a mediocre cocktail. You just mix 80 parts ethanol with 20 parts water. It's not rocket science, but hey, close enough for government work, right? Just don't drink it thinking it's a fancy cocktail - trust me, that's a party foul waiting to happen.
Can you autoclave 1M HCl solution?
It is not recommended to autoclave a 1M HCl solution as autoclaving acids can lead to the generation of corrosive fumes and potential damage to the autoclave equipment. It is safer to prepare fresh 1M HCl solution as needed using appropriate lab practices.
What happens when you put frozen ethanol into liquid ethanol?
When you put frozen ethanol into liquid ethanol, the frozen ethanol will begin to melt and mix with the liquid ethanol. Both states of ethanol will reach an equilibrium temperature, and the frozen ethanol will ultimately dissolve into the liquid ethanol to form a homogeneous solution.
How can we prepare 1M solution of NaCl?
To prepare a 1M solution of NaCl, dissolve 58.44 grams of NaCl in water and dilute to 1 liter with water. This will give you a solution where the concentration of NaCl is 1 mole per liter.
How does one prepare 30 percent ethanol?
30 ml of ethanol to 70ml of distilled water.
How does one prepare 500ml of 70 percent ethanol?
150 ml ethanol to 350 ml distilled water
How do you prepare 1M from 10mM Tris-HCL?
To prepare 1M Tris-HCl from a 10mM solution, you would need to dilute the 10mM solution by a factor of 100. This means you would mix 1 part of the 10mM solution with 99 parts of water to achieve a final concentration of 1M Tris-HCl.
How do you prepare 80 percent ethanol?

How many distilled water will be added to prepare 1000 ml 95 percent ethanol from 1000 ml 99 percent ethanol?
To prepare 1000 ml of 95% ethanol from 1000 ml of 99% ethanol, you will need to add 25 ml of distilled water to the 99% ethanol. This will bring the final ethanol concentration to 95%.
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.

How do you prepare 0.02m Naoh from 1M Naoh solution?
To prepare 0.02M NaOH from 1M NaOH solution, you will need to dilute the 1M solution. Use the formula: C1V1 = C2V2, where C1 is the concentration of the stock solution (1M), V1 is the volume of the stock solution you will use, C2 is the desired concentration (0.02M), and V2 is the final volume of the diluted solution. Calculate the volume of 1M NaOH solution (V1) needed to make the desired 0.02M concentration and dilute it with water to reach the desired volume (V2).
How do you prepare diacetone alcohol from ethanol?
Diacetone alcohol can be prepared from ethanol by first converting ethanol to diacetone by reacting it with acetone in the presence of an acidic catalyst. Diacetone is then hydrogenated to produce diacetone alcohol.
How can you prepare 1M H2SO4?
To prepare 1M H2SO4 solution, you would need to dilute concentrated sulfuric acid (approximately 18M) by adding the appropriate amount of water. To make 1L of 1M H2SO4 solution, you would mix approximately 55.5 mL of concentrated sulfuric acid with about 944.5 mL of water in a volumetric flask while taking proper safety precautions.
How do you prepare 0.2 milli molar DPPH solution in ethanol?
To prepare a 0.2 millimolar (mM) DPPH solution in ethanol, you need to dissolve 0.2 millimoles of DPPH in a final volume of 1 liter of ethanol. First, calculate the molecular weight of DPPH (usually around 394.33 g/mol) to determine the mass needed to dissolve in ethanol. Then add this mass of DPPH to ethanol and make up the volume to 1 liter.
How can prepare ethanolic solution?
To prepare an ethanolic solution, simply mix ethanol (commonly known as alcohol) with a solvent such as water. The ratio of ethanol to water will determine the concentration of the solution. Be sure to measure the quantities accurately and mix well to ensure homogeneity.
