Final answer:

To find the number of glucose molecules in 36.6g, you first calculate the number of moles using the molar mass, then use Avogadro's number to convert moles to molecules. This gives approximately 1.22 x 10^23 molecules of glucose.

Explanation:

To calculate the number of molecules of glucose in 36.6g, you first need to find out how many moles of glucose this mass represents. We know that the molar mass of glucose is 180.156g/mol. Therefore, you can determine the number of moles by dividing the given mass by the molar mass. This gives us 0.203 moles of glucose (36.6g / 180.156g/mol).

Next, to find the number of molecules, we utilize Avogadro's number, which is 6.022 x 10^23 molecules/mol. Multiply the number of moles by Avogadro's number to obtain the number of molecules: 0.203 moles * 6.022 x 10^23 molecules/mol = 1.22 x 10^23 molecules.
