You wish to determine the density of two unknown, immiscible liquids, A and B, at room temperature.  To do this you must measure the mass of a known volume of each liquid.  For  liquid A,  you  decide  to  use  a  volumetric  pipet  to  dispense  exactly  5.00 mL into  a convenient container.  Before dispensing the volume of liquid A into the container, you obtain and record the container’s mass as 2.83 grams.  After adding the 5.00 mL of liquid A to the container you reweigh the liquid containing container and find the combination to have a mass of 7.71-grams. What is the density of liquid A in g/mL?

1.An aqueous solution of manganese (II) iodide,MnI2,is made by dissolving 21.1 grams of manganese(II) iodide in sufficient water in a 250.mL volumetric flask, and then adding enough water to fill the flask to the mark.What is the weight/volume percentage of manganese (II) iodide in the solution? weight/volume percentage =   2. An aqueous solution of iron (II) chloride,FeCl2,is made by dissolving 31.4 grams of iron (II) chlyin sufficient water in a 500. mL volumetric flask,and then adding enough water to fill the flask to the mark.What is the weight/volume percentage of iron (II) chloride in the solution? weight/volume percentage =_____%

What is the molarity of sodium chloride in a solution that is 26.9% by mass NaCl and has a density of 1.08 g/mL? Write your answer as 1.23 with 3 signficant figures and no unit.

A solution is prepared by mixing 626.0 mL of ethanol with 608.0 mL of water. The molarity of ethanol in the resulting solution is 9.054 M. The density of ethanol at this temperature is 0.7893 g/mL. Calculate the difference in volume between the total volume of water and ethanol that were mixed to prepare the solution and the actual volume of the solution. difference in volume: L

Determine the total volume in mL of water a chemist should add if they want to prepare a 0.200 M aqueous solution with 30.2 g of NaCl. Assume the density of the resulting solution is the same as the water.

You are asked to create a 0.35 M solution of calcium chloride (CaCl2) using a 250.0 mL volumetric flask. a. You are asked to create 50.0 mL of 0.15 M CaCl2 from the stock solution you made in (A). Calculate the volume of stock solution you need to create your diluted solution.

An ethanol-water solution has been prepared by dissolving 10 mL of ethanol (d=0.789 g/mol) in a sufficient volume of water to obtain 100 mL of solution with a density of 0.982 g/mol. Obtain the concentration of the solution in at least 3 different units from the simplest to the most complicated.

A student dissolves 2.135 g of potassium chloride in enough water to make 100.00 mL solution. Th student then pipettes 10.00 mL of this solution into a 250.00 mL volumetric flask then fills the flask up to the calibration line with water. What is the concentration of potassium chloride in the 250.00 mL volumetric flask?

Suppose 2.50 g of lead(II) acetate is dissolved in 300. mL of a 35.0 m M aqueous solution of ammonium sulfate. Calculate the final molarity of lead(II) cation in the solution. You can assume the volume of the solution doesn't change when the lead (II) acetate is dissolved in it. Be sure your answer has the correct number of significant digits. M x10 X Ś
