How many grams of sucrose would you need to prepare 10 mL of .01M solution of sucrose(FW+342g/mole)? show your work
How many moles do you need of the final solution? That is M x L = ? moles sucrose.
moles = grams/molar mass. You have moles and molar mass, solve for grams.
To calculate the number of grams of sucrose needed to prepare a 0.01 M solution in 10 mL volume, we need to use the formula:
grams = moles × molar mass
Step 1: Convert the volume of the solution to liters:
10 mL = 10/1000 = 0.01 L
Step 2: Calculate the number of moles:
moles = Molarity × volume (in liters)
moles = 0.01 M × 0.01 L
moles = 0.0001 mol
Step 3: Calculate the grams of sucrose:
grams = moles × molar mass
grams = 0.0001 mol × 342 g/mol
grams = 0.0342 g
Therefore, you would need 0.0342 grams of sucrose to prepare 10 mL of a 0.01 M solution.
