A solution that is refered to as a percentage of something (like potassium hydroxide, KOH) refers to the mass of the solute compared to the total solution, so a 5% KOH solution would be 5g KOH + 95g H2O, and the 5g KOH would be 5% of the 100g total of the solution.

How do you make a 10 percent aqueous solution of potassium hydroxide?
Weigh 10g of the given sample and dissolve it in 100ml of water, it forms a 10% solution of that sample.
How do you make a 1 percent aqueous solution of potassium hydroxide?
1% solution of KOH contains 1g of KOH in 100g of solution. This means that you need to mix 1g of KOH and 99g of water.
Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?
Yes, the potassium and the hydrogen will bond together, leaving the sulfate and calcium.
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 would you make a 1.25 molar solution of potassium hydroxide?
The formula mass of KCl is 75.5 so when 94.375g of it are dissolved in i litre water the solution prepared is 1.25 molar

How do you make saturated potassium hydroxide?
Gradually dissolve potassium hydroxide crystals in pure water. In a certain point, a precipitation starts as further dissolving does not take place and you've made a solution of saturated potassium hydroxide.
How many moles of potassium hydroxide are required to make 200cm3 of 0.5M solution?
0.1 moles
How do you make k2cr2o4 solution?
It is prepared by roasting powdered chromite with potash and limestone, treating the cinder with a hot potassium sulfate solution and leaching.Alternatively, it may be prepared by the reaction of potassium dichromate and potassium hydroxide.
What observations do you make when you react potassium hydroxide with sodium carbonate?
You get a double decomposition reaction, producing sodium hydroxide and potassium carbonate, but actually there is no real reaction; the four substances remain in perfect equilibrium in solution.
If you use potassium hydroxide instead of sodium hydroxide what salt would you make?
potassium chloride
How do you make a 5 percent water solution of sodium hydroxide?
Add 5 g of sodium hydroxide to 95 g (or 95 mL) of water to get a 5% solution.
How many atoms make potassium hydroxide?
The chemical formula of potassium hydroxide is KOH.So, potassium hydroxide has 3 atoms in the formula.The dissociation equation is:KOHK+ + (OH)-
Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?
Yes, the potassium and the hydrogen will bond together, leaving the sulfate and calcium.
What elements make pottasium hydroxide?
potassium hydroxide: KOH K: potassium O: oxygen H: hydrogen
How would you make a 1.25 molar solution of potassium hydroxide?
