An aqueous solution of acetone is made by transfering 38.1 mL of liquid acetone to a 500. mL volumetric flask, and then adding enough water to fill the flask to the mark. What is the volume/volume percentage of acetone in the solution?

A chemist prepares a solution of potassium bromide    KBr    by measuring out  0.17g  of  KBr  into a  300.mL  volumetric flask and filling to the mark with distilled water.   Calculate the molarity of  Br−  anions in the chemist's solution.   Be sure your answer is rounded to  2  significant digits.

In the laboratory, a student dilutes 13.5 mL of a 8.75 M hydrochloric acid solution to a total volume of 150.0 mL. What is the concentration of the diluted solution? Concentration =  M

A student wants to make a 0.600 M aqueous solution of barium sulfate, BaSO4, and has a bottle containing 12.00 g of barium sulfate. What should be the final volume of the solution?   Find the numerical answer for this question and make sure to include the following: What is the formula for molarity? What is the molar mass for barium sulfate? When you give your numerical answer, what are the correct significant figures and how do you know that is the correct amount?

Enter your answer in the provided box. Ordinary household bleach is an aqueous solution of sodium hypochlorite. What is the molarity of a bleach solution that contains 23.4 g of sodium hypochlorite in a total volume of 295 mL? M

Suppose 0.247 g of nickel(II) chloride is dissolved in 150. mL of a 17.0 m M aqueous solution of potassium carbonate. Calculate the final molarity of chloride anion in the solution. You can assume the volume of the solution doesn't change when the nickel(II) chloride is dissolved in it. Round your answer to 3 significant digits.
