how many molecules are present in 1.2 mol of glucose, C6H12O6?
same as in 1.2 mol of anything:
1.2*6.023*10^23 = 7.228*10^23
thanks steve :)
To find the number of molecules present in 1.2 moles of glucose (C6H12O6), you first need to calculate the Avogadro's number, which is 6.022 × 10^23 molecules/mol. Then, you can use the following formula:
Number of molecules = Number of moles × Avogadro's number
Substituting the given values:
Number of molecules = 1.2 mol × 6.022 × 10^23 molecules/mol
Calculating the result:
Number of molecules = 7.2264 × 10^23 molecules
Therefore, there are approximately 7.23 × 10^23 molecules in 1.2 moles of glucose (C6H12O6).
To determine the number of molecules present in a given amount of substance, you can use Avogadro's number, which states that one mole of any substance contains 6.022 × 10^23 particles (atoms, molecules, etc.).
In this case, you are given 1.2 mol of glucose, C6H12O6. Since glucose is a molecular substance, we can directly relate the number of moles to the number of molecules using Avogadro's number.
Step-by-step calculation:
1. Determine the number of molecules in 1 mole of glucose:
- The chemical formula of glucose is C6H12O6, indicating that for every molecule of glucose, there are 6 carbon atoms (C), 12 hydrogen atoms (H), and 6 oxygen atoms (O).
- Calculate the total number of atoms per molecule of glucose: 6 carbon atoms + 12 hydrogen atoms + 6 oxygen atoms = 24 atoms.
- Since 1 mole of any substance contains 6.022 × 10^23 particles, 1 mole of glucose contains 6.022 × 10^23 molecules.
2. Calculate the number of molecules in 1.2 mol of glucose:
- Multiply the number of molecules in 1 mole of glucose by the number of moles given.
- Number of molecules = (6.022 × 10^23 molecules/mole) × (1.2 mol)
- Calculate the result to find the number of molecules.
Now, plug in the numbers and calculate to find the answer.
