How many grams needed from water to prepare 160 grams from potassium acetate 5 percent w?
To prepare 160 grams of potassium acetate with a 5% w/w concentration, you would need to calculate the mass of the potassium acetate in the solution. Since the concentration is given as a percentage by weight, 5% of 160 grams is 8 grams of potassium acetate. The remaining mass in the solution would be water. Therefore, you would need 152 grams of water to prepare 160 grams of potassium acetate with a 5% w/w concentration.

How can you test the percent purity of potassium chlorate?
To test the percent purity of potassium chlorate, you can perform a titration with a known concentration of a reducing agent, such as iron(II) sulfate, and determine the amount of reducing agent needed to completely react with the potassium chlorate. From the titration results, you can calculate the purity of the potassium chlorate by comparing the actual amount of potassium chlorate in the sample to the theoretical amount that should be present based on the reaction stoichiometry.
What volume of 5 percent aluminum acetate solution will be needed if 120 ml of 0.05 percent solution is extemporaneously compounded for patient use?
To calculate the volume needed, you can use the formula C1V1 = C2V2, where C1 is the concentration of the initial solution, V1 is the initial volume, C2 is the concentration of the final solution, and V2 is the final volume. Plugging in the values, you get (0.05)(120) = (5)(V2), which simplifies to V2 = 1.2 ml. Therefore, 1.2 ml of the 5% aluminum acetate solution will be needed.
