starting with solid sucrose describe how you would prepare 125ml of. 150 M sucrose solution
To prepare a 150 M sucrose solution starting with solid sucrose, follow these steps:
Step 1: Calculate the molecular weight of sucrose
The molecular weight of sucrose, also known as table sugar, is 342.3 g/mol.
Step 2: Determine the amount of solid sucrose needed
To make a 150 M solution, you need to dissolve an amount of sucrose that will yield a total of 150 moles per liter of solution.
In 1 liter of solution, the mass of sucrose needed can be calculated using the formula:
mass of sucrose (g) = molarity (mol/L) x molecular weight (g/mol) x volume (L)
In this case, we want to prepare a 125 ml solution, which is equivalent to 0.125 L.
mass of sucrose (g) = 150 mol/L x 342.3 g/mol x 0.125 L
mass of sucrose (g) = 6410.625 g
Therefore, you need approximately 6410.625 g of solid sucrose.
Step 3: Dissolve the solid sucrose in a suitable solvent
You can dissolve the solid sucrose in water to make the desired sucrose solution. Follow these steps to dissolve the solid sucrose:
- Weigh out approximately 6410.625 g of solid sucrose using a balance.
- Pour the solid sucrose into a clean and dry container suitable for mixing solutions.
- Add water to the container, stirring continuously until all the solid sucrose is dissolved. It may take some time and gentle heat can be used to facilitate the dissolution process, if necessary.
- Continue adding water until the final volume reaches 125 ml, ensuring that the sucrose is completely dissolved in the solvent.
Step 4: Measure and adjust the final concentration
After dissolving the solid sucrose and reaching a final volume of 125 ml, you can measure the solution's concentration using a suitable analytical method like spectrophotometry or titration. Based on the measured concentration, you can adjust the solution by adding more solvent or solid sucrose to achieve the desired 150 M concentration.
Note: Handling large amounts of solid sucrose can be challenging, so it is advisable to work with smaller quantities and scale up the procedure accordingly if a 125 ml solution is needed. Additionally, it is important to follow safety guidelines and wear appropriate protective equipment when working with chemicals.
To prepare a 150 M sucrose solution starting with solid sucrose, you would need the molar mass of sucrose and the desired volume of the solution. Here's a step-by-step guide on how to calculate the necessary amount of solid sucrose:
1. Determine the molar mass of sucrose: The molar mass of sucrose (C12H22O11) can be calculated by summing up the atomic masses of all the elements present. The atomic masses can be found in the periodic table. In this case, the molar mass of sucrose is approximately 342.30 g/mol.
2. Calculate the amount of solid sucrose needed: To make 125 ml of a 150 M sucrose solution, you need to determine the number of moles required. The formula to calculate the number of moles is:
Moles = Molarity × Volume (in liters)
In this case, Moles = 150 mol/L × 0.125 L = 18.75 mol.
3. Convert moles to grams: Now that you know the number of moles needed, you can convert it to grams using the molar mass of sucrose. The formula to convert moles to grams is:
Grams = Moles × Molar Mass
In this case, Grams = 18.75 mol × 342.30 g/mol = 6405.375 g.
Therefore, you would need approximately 6405.375 grams of solid sucrose to prepare a 125 ml solution of 150 M concentration.
It's important to note that 150 M is a high molarity concentration, and the solubility of sucrose might be limited. Make sure to consult solubility tables or experimental data to verify that such a concentrated sucrose solution is feasible.
mass sucrose= volume*molarity*molmass
= .125*.150*molmassSucrose
So here is what I would do. Take that mass, put it in a beaker or cylinder, depending on how accurage you want it, add distilled water to the 125ml mark, then stir, put in a container, label properly, then properly store the container.
