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 you prepare 3 percent solution of hydrogen peroxide?
1 part of hydrogen peroxide out of 30% hydrogenperoxide bottle add 10 parts of distilled water
A chemist has one solution that is 80 percent acid and another solution that is 30 percent acid How much of the first 80 percent solution is needed to make a 400 L solution that is 62 percent acid?

A solution contains 30 g of calcium chloride in 250 g of water express the mass percent?
The solution has a total mass of 30 + 250 = 380 g. The mass percent of calcium chloride in this solution is 100(30/380) = 7.9 %, to the justified number of significant digits.
Cell that contains 50 percent water is placed in a solution that is 30 percent water The cell and the solution will reach equilibrium when they both contain how much water?
The cell and the solution will reach equilibrium when they each contain 40 percent water. This equilibrium is achieved through osmosis.
