How many acetone molecules are in a bottle of acetone with a volume of 330 ml?
The number of acetone molecules is 24,843.10e23.
How many grams in 1 percent solution?
A 1% solution normally contains 1 gram of active ingredient per 100 ml of solution (weight-volume percent) Could also be 1gm per 100 gms (weight-weight percent)- but normally weight-volume is used.
Does caffeine dissolve in acetone?
Caffeine is soluble in water - but not HIGHLY soluble. You can dissolve a lot more caffeine in the same volume of water compared to what will dissolve in an equal volume of acetone. It dissolves better in hot acetone than in cold acetone.
What would happen if 50 percent of the water in the solution evaporated?
The volume reach the half.
Does acetone changes volume when combined with water?
Yes. Due to the Law of the Conservation of Matter, anything combined with water will increase in volume, because water itself has volume, which is not lost by combining water with anything else.
What is the percent by volume concentration of 78.9 mL of acetone in 1550 mL of an acetone-water solution?
1550 mixture-----------------78,9 acetone100 mixture-------------------xx = 78,9 x 100/1559 = 5,09The concentration of acetone is 5,o9 %.
The concentration of alcohol and water solution is 25 percent alcohol by volume what is volume of alcohol and 200 lM of solution?
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
What is the percent by volume of a solution formed by mixing 25mL of isopropanol with 45 mL of water?
% V / V (percentage of volume per volume) =? V1 (solute volume) = 25 mL V (volume of the solution) = solute + solvent = 25 mL + 45 mL = 70 mL We apply the data to the formula of volume percentage of the solute per volume of solution, we will have:
How do you dilute 20 volume hydrogen peroxide to make a 3 percent solution?
20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.
How can you express the solution in percent by volume?
Per cent by volume means mls of solute per 100 mls solution. So you need to know the volume of the solute and the total volume of the solution. Divide volume of solute by volume of solution and multiply by 100 to get per cent by volume.
What is the volume in ml of 6.54 g of acetone?
What is the volume, In millimeter of 6.68 g of acetone ?
What is the percentage of volume?
Volume percent (v/v %) is defined as: volume percent = [(volume of solute) / (volume of solution)] x 100% Volume percent is handy when preparing solutions of liquids. Concentration of a solution can be stated in volume percentages. Be aware that volume of solution is in formula denominator, not volume of solvent. Thus to get 10% v/v solution of ethanol in water you can take 10 ml of ethanol and add enough water to have total 100 ml of resulting solution. It is worth to mention volumes of solute and solvent cannot be simply added to get volume of solution. For instance if you add 10 ml of ethanol to 90 ml of water the volume of the solution will be less than 100 ml.
How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare 6 nM ammonium hydroxide a 30 percent solution you need to know the volume of the 30 percent solution that you have and the volume of 6nM solution you would like to make. Then use the following formula: C1V1 = C2V2 where C = concentration in moles/Liter and V = volume in liters.
How do make a percent sucrose solution?
Calculate the weight of sucrose for the desired volume and concentration of the solution.
How many acetone molecules are in a bottle of acetone with a volume of 330 ml?
The number of acetone molecules is 24,843.10e23.
What is the volume of alcohol present in 200.0 ml of a 55 percent by volume solution of alcohol?
The volume of alcohol is 110 mL.
How do you make a 3 percent solution from a 40 percent solution?
This depends on the volume of the 40 percent solution you have. The question can be rewritten as: 40%a/(a+b) = 3% where a is the volume of the 40% solution, and b is the volume of water we need to add. Multiply both sides by (a+b) to get: 40%a = 3%a + 3%b Subtract 3%a from both sides to get 37%a = 3%b Divide by 3% to get: 12.3333...a = b Thus whatever the current volume is, you need to add 12.33333 times that volume in water in order to get a 3% solution.
