Calculate the molarity of the solution when 14 mL of solution contains 0.128 g of ammonium phosphate. Is a molar mass needed for this calculation? Enter either yes or no. If so, calculate the molar mass using our periodic table and enter with the proper s.f. If not, enter 0. Do not include units. g/mol In the three blanks, enter the results of the calculation: value (decimal notation with proper s.f.), units, and substance (in this order).

A barium hydroxide solution is prepared by dissolving 3.22 g of Ba(OH), in water to make 58.1 mL of solution. What is the concentration of the solution in units of molarity? concentration: The barium hydroxide solution is used to titrate a perchloric acid solution of unknown concentration. Write a balanced chemica equation to represent the reaction between barium hydroxide and perchloric acid. chemical equation: If 18.5 ml of the barium hydroxide solution was needed to neutralize a 8.04 mL aliquot of the perchloric acid solution, what is the concentration of the acid? concentration:

4.67 g of cobalt(II) sulfate are dissolved in water to make 2600. mL of solution. Calculate the molarity. Isa molar mass needed for this calculation? Enter either yes or no, If so, calculate the molar mass using our periodic table and enter with the proper s.f. If not, enter 0. Do not include units. g/mol In the three blanks, enter the results of the calculation: value (decimal notation with proper s.f.)., units, and substance (in this order).

Converting Concentrations to Different Units   Introduction:   Depending on how the concentration unit is defined, concentration can serve as a conversion between the amount of a solute and the amount of a solution or solvent. Concentrations can therefore be helpful in a number of stoichiometry issues. The original definition of the concentration unit is frequently preferred because it contains the conversion factor.  Today, for chemists, it is suitable to make a solution in the lab using a specific concentration unit like molarity, and then convert the concentration to another unit. Today in the lab, I will prepare a sodium bicarbonate (baking soda) solution with a specific molarity. I will then translate the concentration into molality, mass percent, and mole fraction.   Procedure   The first step of this lab was to make sure I had everything I needed and that my surroundings were safe. I then looked at an empty beaker weighing paper and a balance. I first took a piece of weighing…
