Final answer:

A molecule of glucose (C6H12O6) contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

Step-by-step explanation:

To calculate the number of molecules of glucose, use the equation: Number of molecules = Number of moles x Avogadro's number. Given the mass of glucose, divide it by the molar mass of glucose to obtain the number of moles and then use Avogadro's number to calculate the number of molecules.

A molecule of glucose (C6H12O6) contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. To determine the number of molecules of glucose, we need to use Avogadro's number, which states that 1 mole of any substance contains 6.022 x 10^23 molecules. The molar mass of glucose is 180.16 g/mol.


To calculate the number of molecules of glucose, we can use the equation:

Number of molecules = Number of moles x Avogadro's number

Given that the mass of glucose is 372.15 g, we can calculate the number of moles:

Number of moles = Mass of glucose / Molar mass of glucose = 372.15 g / 180.16 g/mol = 2.065 moles


Finally, we can calculate the number of molecules:

Number of molecules = 2.065 moles x 6.022 x 10^23 molecules/mole = 1.243 x 10^24 molecules
