(Volume)(1.00 M) = (75.0 ml)(12 M)
(Volume)(1.00 M) = (900)
Volume = 900 ml
-----------------------
The value is 33,3 %.
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
To make a 10 volume developer solution from a 20 volume developer solution, you can dilute the 20 volume developer with an equal amount of distilled water. This will effectively reduce the concentration of the developer solution by half, resulting in a 10 volume developer. For example, if you have 100 ml of 20 volume developer, you would mix it with 100 ml of distilled water to create 200 ml of 10 volume developer.
Assuming you want 0.1% weigh/volume, you dissolve 0.1 g mercuric chloride in 100 ml of solution. So, you would weigh out 0.1 g (100 mg) of solid and dissolve in enough solvent to make a final volume of 100 ml.
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
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.
It means it has 42% alcohol in a 100% solution. vv% = volume/volume % So a concentrate (v/v%) =volume solute/volume of solution * 100. So 42/100 x 100 = 42 vv%
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.
Dilute a measured volume of the 100 mM solution with 19 times its own volume of pure water to produce a 5mM 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
40% of 750ml = (40/100) * 750 = 300 mL.
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.
To prepare 1 M CaI aqueous solution, dissolve 29.4 g in a total volume of 100 mls, or 294 g in a total volume of 1 liter.
Assuming you want 0.1% weigh/volume, you dissolve 0.1 g mercuric chloride in 100 ml of solution. So, you would weigh out 0.1 g (100 mg) of solid and dissolve in enough solvent to make a final volume of 100 ml.
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
