Explain in detail how to prepare 250. mL of a 0.125 M glucose solution. The formula for glucose is C6H12O6.

determine the mole mass of glucose.

Now find the mass of glucose needed
Mass=Molarity*volumeinliters*molmass
= .125*.250*molmass

take that mass, add water sufficent to make 250ml, stir, label, and store.

To prepare a 250 mL, 0.125 M glucose solution, you will need to follow these steps:

Step 1: Calculate the molar mass of glucose (C6H12O6).
The molar mass of carbon (C) is approximately 12.01 g/mol, hydrogen (H) is approximately 1.01 g/mol, and oxygen (O) is approximately 16.00 g/mol. Since glucose (C6H12O6) contains 6 carbons, 12 hydrogens, and 6 oxygens, we can calculate the molar mass as follows:

Molar mass of glucose (C6H12O6) = (12.01 g/mol x 6) + (1.01 g/mol x 12) + (16.00 g/mol x 6) = 180.18 g/mol

Step 2: Calculate the grams of glucose needed.
Using the molar mass of glucose, we can calculate the grams of glucose required to prepare the solution by using the formula:

Grams of glucose = Molarity (mol/L) x Volume (L) x Molar mass (g/mol)

Since the molarity is given as 0.125 M and the volume is 250 mL (0.250 L), we can substitute these values into the equation:

Grams of glucose = 0.125 mol/L x 0.250 L x 180.18 g/mol = 5.63 g

Therefore, you will need approximately 5.63 grams of glucose to prepare the solution.

Step 3: Dissolve the calculated amount of glucose in water.
Measure out 5.63 grams of glucose using a balance and transfer it to a container or beaker. Add a small amount of distilled water and stir until the glucose is completely dissolved.

Step 4: Transfer the solution to a 250 mL volumetric flask.
Once the glucose is dissolved, transfer the solution to a 250 mL volumetric flask. Rinse the container used to dissolve the glucose with distilled water and add it to the volumetric flask. Fill the flask up to the calibration mark using distilled water, ensuring that the bottom of the meniscus rests on the mark.

Step 5: Mix the solution.
After filling the volumetric flask to the mark, carefully mix the solution by inverting the flask several times or by using a stirrer rod, ensuring that the solution is thoroughly mixed.

Now, you have successfully prepared a 250 mL, 0.125 M glucose solution.
