To make a 0.5 M solution of glucose, we need to dissolve 0.5 moles of glucose in 1 liter of water. The molar mass of glucose is 180 g/mol. Therefore, to make a 0.5 M solution of glucose, we need (0.5 mol/L) x (180 g/mol) = 90 g/L of glucose. Option B suggests dissolving 90 g of glucose in a small volume of water, and then adding more water until the total volume of the solution is 1 L, which is the correct procedure. Option A suggests dissolving 0.5 g of glucose, which is not enough to make a 0.5 M solution. Option C suggests dissolving 180 g of glucose, which is enough to make a 1 M solution, not a 0.5 M solution. Option D suggests dissolving 0.5 g of glucose in 1 L of water, which would make a solution that is much less concentrated than 0.5 M. Option E suggests dissolving 180 g of glucose in only 0.5 L of water, which would result in a solution that is more concentrated than 0.5 M.
