Question

Can you prepare 1 liter of a 0.5-molar glucose solution? Show your work here.

a) Yes, by dissolving 18 g of glucose in 1 liter of water.
b) No, because glucose doesn't dissolve in water.

Answer 1

Yes, you can prepare a 1 liter 0.5-molar glucose solution by dissolving 18 g of glucose in 1 liter of water.

Step-by-step explanation:

Yes, you can prepare a 1 liter 0.5-molar glucose solution by dissolving 18 g of glucose in 1 liter of water. To calculate the amount of glucose needed, you can use the formula:

Amount of glucose (in moles) = molarity x volume (in liters)

For a 0.5-molar solution, the amount of glucose needed would be:

0.5 mol/L x 1 L = 0.5 moles of glucose

To convert moles of glucose to grams, you can use the molar mass of glucose which is approximately 180.2 g/mol. Therefore:

0.5 moles x 180.2g/mol = 90.1 grams of glucose

So, by dissolving 90.1 grams of glucose in 1 liter of water, you can prepare a 0.5-molar glucose solution.
