What is the molarity of a glucose solution that contains 10.0 g of C₆H₁₂O₆ (180.18 g/mol)dissolved in 100.0 mL of solution?

Question

Quizplus · Accepted Answer

First we need to calculate the number of moles of glucose:

moles of glucose = mass of glucose / molar mass of glucose = 10.0 g / 180.18 g/mol = 0.0555 mol

Then we need to calculate the volume of solution in liters:

100.0 mL = 100.0 mL x (1 L / 1000 mL) = 0.100 L

Finally, we can calculate the molarity of the solution:

molarity = moles of solute / liters of solution = 0.0555 mol / 0.100 L = 0.555 M

Therefore, the best choice is C.
