Calculation of the Number of Sugar Molecules in a Teaspoon of Powdered Sugar

To calculate the number of sugar molecules in a teaspoon of powdered sugar, we need to determine the number of moles of sugar in the given portion and then convert it to the number of molecules.

Given: - Amount of powdered sugar: 0.1 moles of sugar molecules

To calculate the number of molecules, we can use Avogadro's number, which states that there are approximately 6.022 x 10^23 molecules in one mole of a substance.

Using this information, we can calculate the number of sugar molecules in the given portion:

Step 1: Calculate the number of molecules in 1 mole of sugar: - Avogadro's number = 6.022 x 10^23 molecules/mol

Step 2: Calculate the number of molecules in 0.1 moles of sugar: - Number of molecules = (0.1 moles) x (6.022 x 10^23 molecules/mol)

Let's perform the calculation:

Number of molecules = (0.1 moles) x (6.022 x 10^23 molecules/mol)

Number of molecules = 6.022 x 10^22 molecules

Therefore, there are approximately 6.022 x 10^22 sugar molecules in a teaspoon of powdered sugar. [[1]]

Calculation of the Amount of Substance of Each Chemical Element in 1 Mole of C6H12O6

To determine the amount of substance (in moles) of each chemical element in 1 mole of C6H12O6 (glucose), we need to analyze the molecular formula of glucose and identify the number of atoms of each element present.

The molecular formula of glucose (C6H12O6) indicates that it contains 6 carbon (C) atoms, 12 hydrogen (H) atoms, and 6 oxygen (O) atoms.

Therefore, in 1 mole of glucose (C6H12O6), we have: - 6 moles of carbon atoms (C) - 12 moles of hydrogen atoms (H) - 6 moles of oxygen atoms (O)

Hence, in 1 mole of C6H12O6, there are: - 6 moles of carbon atoms (C) - 12 moles of hydrogen atoms (H) - 6 moles of oxygen atoms (O)

Please note that the calculation is based on the molecular formula of glucose and the assumption that all atoms are present in the compound. [[2]]
