Answer:
Therefore, you would need 21.568 g of sucrose to make a .125M solution in a 500 ml volumetric flask.
Step-by-step explanation:
To calculate the number of grams of solute you would need to make a .125M sucrose solution in a 250 ml volumetric flask, you can use the following formula:
grams of solute = (Molarity x Volume x Molecular weight) / 1000
Copy
where:
Molarity = 0.125 M
Volume = 250 ml = 0.25 L
Molecular weight of sucrose = 342.3 g/mol
Substituting these values into the formula gives:
grams of solute = (0.125 x 0.25 x 342.3) / 1000
grams of solute = 10.784 g
To calculate the number of grams of solute you would need to make a .125M sucrose solution in a 500 ml volumetric flask, you can use the same formula as above but with a different volume:
grams of solute = (Molarity x Volume x Molecular weight) / 1000
where:
Molarity = 0.125 M
Volume = 500 ml = 0.5 L
Molecular weight of sucrose = 342.3 g/mol
Substituting these values into the formula gives:
grams of solute = (0.125 x 0.5 x 342.3) / 1000
grams of solute = 21.568 g
Therefore, you would need 21.568 g of sucrose to make a .125M solution in a 500 ml volumetric flask.
