What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
Percent by Volume of Solute in Solvent = Volume Solute/ (Volume Solvent + Volume Solute) * 100% = 48/ 192 = 25%
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 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.
How much sugar is there in 100mL of a10 percent aqueous sugar solution and what is the solvent in the solution?
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g
What information is necessary to determine the molarity of a solution if the chemical formula of the solute is known?
You know the chemical formula. You can get the molecular weight from this. You need the end volume and you also need the mass of solute.
How many grams of solute is present in 20 mL of a 2 percent vooumbe by volume solution of a solute that has a specific gravity of 0.962 contain?
it has exactly 29.34098 grams of solute
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.
What is the formula of the percent of volume and percent of mass?
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
What is a concentration of a solution?
The concentration of a solution is basically how strong the solution is.
Mole percent vs volume percent?
Mole percent vs volume percent is a simple comparison to make. Mole percent is equivalent to moles of substance/moles of total x 100. Volume percent is volume of substance/volume of total x 100.
How can you determine molarity from percent purity of solution?
Molarity is the no of moles of solute dissolved per litre of a solution. now if u want to find it from the percentage purity , here is the formula for that Molarity = % purity x density x 10 ___________________ molar weight of the solute note : density is usually given %purity problems, if its not u can evualvate it from from formula { d= mass/volume} i hope it solves the problem
What is the meaning formula of percent by volume?
If you have a 70cl bottle of whisky which is "40% alcohol by volume" it contains 28cl of alcohol.
