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…

What occurs when aqueous lithium hydroxide, LiOH, reacts with aqueous magnesium chloride, MgCl2 ? Select one: O LIOH forms as a precipitate. O MgCl, forms as a precipitate. O No precipitate forms and no reaction occurs. O Mg(OH)2 forms as a precipitate O LICI forms as a precipitate.

13. Nitric acid, HNO3, is a strong acid in aqueous solutions. It is sold commercially as a concentrated solution with a density of 2.14 kg.L-¹ and containing 58% mass of HNO3. We introduce 10.0 mL of this solution in a 250.00 mL volumetric flask which is then filled to the mark with distilled water. This solution is called S. S is then diluted 100 times to afford solution S'. a. What is the definition of a strong acid? | b. What is the concentration of solution S"? c. What is the pH of solution S'?
