Answer:
0.5 M glucose solution is more concentrated.
Explanations
What is concentration?
Concentration is defined as the measure of how much of a given substance there is mixed with another substance.
From the question given, we are to determine which of the solution is more concentrated.
For the 0.5% glucose solution, we will convert it to molarity as shown:
0.5% glucose solution means that there are 0.5 grams for each 100mL of the solution.
Since the molarity is obtained in mol/L of solution, 1L of the solution will conatin 5g of glucose.
Molarity = Mass/Molar mass of glucose
Molarity = 5g/180.156 = 0.028M
Since 0.028M glucose solution is less than 0.5M glucose solution, this shows that 0.5 M glucose solution is more concentrated.
