Chemistry Solutions Practice Problems 1. Describe how you would prepare 1 L of a 1 M solution of sodium chloride.
The gram formula weight of sodium chloride is To make a 1 M solution of sodium chloride, dissolve When all the solid is dissolved and the solution is at room temperature, dilute to the mark and invert the flask several times to mix.
Describe how you would prepare 1 L of a 2 M solution of acetic acid.
The gram formula weight of acetic acid is To make a 2 M solution of acetic acid, dissolve Since acetic acid is a liquid, it may also be measured by volume. Divide the mass of acid by its density 1. Swirl the flask gently to mix the solution.
Once the solution is at room temperature, dilute to the mark and invert the flask several times to mix. Describe how you would prepare g of a solution that is 0. Since the solute phenolphthalein is a solid, the solution is percent by mass. Mass percent means the number of grams of solute per g of solution.
To prepare the solution, dissolve 0. Volume percent means the number of milliliters of solute per mL of solution. Dilute 22 mL acetic acid with distilled or deionized water to make mL of solution.
Describe how you would prepare 1. Calculate the volume of 3. Once the solution is at room temperature, dilute to the mark with water and invert the flask several times to mix.
Describe how you would prepare mL of a 0. Calculate the volume of 5. Describe how you would prepare mL of a 1.Feb 23, · A mixture initially contains moles each of N2 and O2 in an L vessel.
