Which solution contains smallest mass of glucose? please show calculations

Which solution contains the smallest mass of glucose (MM = 180. g/mol)? 100.0 mL of a 1.0 m solution of glucose (assume density of water = 1.0 g/mL and that the glucose added no volume) all contain the same mass of glucose 100.0 g of a solution that is 0.10 mole fraction glucose 100.0 mL of a 1.0 m solution of glucose (assume density of water = 1.0 g/mL and that the glucose added no volume) 100.0 g of a solution that is 10% glucose by mass 100.0 mL of a 1.0 M solution of glucose

Explanation / Answer

Solution :-

Lets calculate the mass of glucose in each solution

b) 100 g solution that is 0.1 moe fraction of glucose

means mole fraction of water is 0.9

c) 100 ml 1.0 m solution of glucose

1 m * 0.100 kg = 0.1 mol glucose

0.1 mol glucose *180 g per mol = 18 g glucose

d) 100 g solution that is 10 5 of glucose means 10 g of glucose

e) 100 ml of M solution

1 mol per L * 0.100L = 0.1 mol glucose

0.1 mol glucose * 180 gper mol = 18 g glucose

Solution d have only 10 g of glucose so the answer is solution d
