If a 0.5 M solution of glucose is prepared, and 1 mole of glucose has a mass of 180 g, how much glucose in grams is needed to make 2 L of this solution?

  • A: 90 g
  • B: 180 g
  • C: 360 g
  • D: 45 g

Explanation

To find the mass of glucose needed, first calculate the total moles required: Moles = Molarity × Volume = 0.5 mol/L × 2 L = 1 mol. Then, convert moles to mass: Mass = Moles × Molar Mass = 1 mol × 180 g/mol = 180 g.
