a solution is prepared by dissolving 8.25 g ammonium sulfate to make 100.0 ml of solution. A 10.0 ml sample of this solution is then diluted to double its volume. Find the concentration of the final solution.
Suppose 1.55 g of barium nitrate is dissolved in 250. mL of a 52.0 m M aqueous solution of ammonium sulfate. Calculate the final molarity of nitrate anion in the solution. You can assume the volume of the solution doesn't change when the barium nitrate is dissolved in it Round your answer to 3 significant digits.
Suppose 0.0793 g of potassium chloride is dissolved in 100. mL of a 20.0 m M aqueous solution of ammonium sulfate. Calculate the final molarity of potassium cation in the solution. You can assume the volume of the solution doesn't change when the potassium chloride is dissolved in It. Be sure your answer has the correct number of significant digits.

Determine how many grams of ammonium phosphate would be needed to prepare 650 mL of 3.5% (m/v) ammonium phosphate solution. Express in scientific notation.
You need to prepare 200 mL of a 0.4 M solution of ammonium hydroxide (NH4OH) You have 80 mL of a 0.5 M NHOH solution and 40 mL of a 7.5% (w/v) NH4OH solution. What volume of 7.5% NHOH and water needs to be added to the 80 mL of 0.5 M NH4OH solution to make up 200 mL of 0.4 M NH4OH? Molar mass of NH4OH 35.04 g/mol % (weight / volume) means mass (in g) in volume (100...
How do you prepare 500 ml of 30% v/v ethanol? How do you prepare 225 ml of 25% w/v NaCl? You have a 20 ml of a 10% w/v solution of ammonium sulfate. How many grams of ammonium sulfate are in this solution? You want to run a cesium chloride gradient to purify a sample of DNA in an ultracentrifuge.
