Oh honey, it's not rocket science. Just measure out 30 grams of table salt and dissolve it in enough water to make 100 grams of solution. Voila, you've got yourself a 30% NaCl solution. Just don't go drinking it thinking it's a margarita, okay?

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?

To create a 400 L solution that is 62% acid, you would need 200 L of the 80% acid solution and 200 L of the 30% acid solution. This would result in a final solution with the desired concentration.


How do you prepare 3 percent of hydrogen peroxide from 30 percent of hydrogen peroxide?

To prepare 3% hydrogen peroxide from 30% hydrogen peroxide, you need to dilute the 30% solution with water. The formula to calculate the dilution is C1V1 = C2V2, where C1 is the initial concentration (30%), V1 is the volume of the initial solution, C2 is the final concentration (3%), and V2 is the final volume of the solution you want to prepare. By plugging in the values, you can determine the volume of 30% hydrogen peroxide needed and the volume of water needed to achieve a 3% solution.


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.

How do you prepare 30 percent of methanolic KOH solution?

To prepare a 30% methanolic KOH solution, you would mix 30g of KOH with enough methanol to make a total solution volume of 100mL. This would result in a solution where 30% of the total weight comes from KOH. Be cautious when handling KOH as it is a caustic substance and should be handled with appropriate precautions.
