Question

If you were presented with 2 liters of a 2m sucrose stock solution, how many grams of sugar would be in a 100ml aliquot?

Answer 1

68.46 gms

Step-by-step explanation:

2 molal solution means there is 2 moles of sucrose per kg of solvent (generally 1000 cc)

2 moles / 1000 ml * 100 ml = .2 moles

mole weight of sucrose = 342.3 gm/mole

342.3 gm/mole * .2 mole = 68.46 gms
