Molarity = moles of solute/Liters of solution Molarity = 25 moles sucrose/50 liters H2O = 0.5 M sucrose
Is that 0.5L ? If yes, as 1L=1dm3, no. of mole= (volume)(concentration)=(0.5)(2)=1 mol

20 grams /385, x 1000 is 51.948 grams per litre. The molecular weight of sucrose is 342.3g/mol. 51.948/342.3 is 0.15176 molar.
The potato is naturally very low in sugars. Although a potato contains three types of sugars; sucrose, fructose and glucose, the average potato is less than one percent sugar.

Molarity (M) represents the moles of a solute per liter of a solvent. In this case, sucrose is the solute and water is the solvent. First, convert your 125g of sucrose to moles...molar mass of sucrose = 342.34 soo you have .365 moles of sucrose. Since you have exactly one L of solution, the molarity of the solution is .365 M Molarity (M) represents the moles of a solute per liter of a solvent.

Change in mass depends on the concentration of sucrose within the dialysis bags. If the concentration of sucrose is greater inside the bag than outside, then water will move into the bag. If the concentration of sucrose is lower inside the bag than outside, then water will move out of the bag.

Molarity = moles of solute/Liters of solution Molarity = 5 moles sucrose/0.5 Liters = 10 M ----------
15 grams sugar per liter is the concentration, in terms of mass per volume. To express the concentration in molarity (assuming the sugar is sucrose): 15 g sucrose * (1 mole sucrose / 342 g sucrose) / 1 L = 0.0439 M aqueous sucrose

Molarity is defined as moles solute/liter of solution.Moles of solute = 2.5 moles sucrose Liters of solution = 0.5 liters Molarity (M) = 2.5 moles/0.5 liters = 5 M
