how many C atoms are in 1.50 moles of lactic acid?
1 mole of lactic acid will contain 6.022 x 10^23 molecules of lactic acid; therefore, 1.5 moles will contain xxxx molecules.
The formula of lactic acid is C3H6O3 so there are three times as many C atoms as there are molecules of lactic acid.
To calculate the number of carbon (C) atoms in 1.50 moles of lactic acid, we need to know the chemical formula of lactic acid, which is C3H6O3.
The chemical formula indicates that each molecule of lactic acid contains 3 carbon atoms. Therefore, to find the number of carbon atoms in 1.50 moles of lactic acid, we need to multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms per mole) and then multiply by the number of carbon atoms per molecule (3).
The calculation is as follows:
Number of carbon atoms = (1.50 moles) x (6.022 x 10^23 atoms/mole) x (3 carbon atoms/1 molecule)
Number of carbon atoms = 9.033 x 10^23 atoms
Therefore, there are approximately 9.033 x 10^23 carbon atoms in 1.5 moles of lactic acid.
To find the number of carbon (C) atoms in a given amount of lactic acid, you need to know the molar mass of lactic acid and the Avogadro's number.
Here's how you can calculate it step by step:
1. Determine the molar mass of lactic acid (C3H6O3):
- C = 12.01 g/mol (atomic mass of carbon)
- H = 1.01 g/mol (atomic mass of hydrogen)
- O = 16.00 g/mol (atomic mass of oxygen)
- Total molar mass = (3 * C) + (6 * H) + (3 * O)
2. Calculate the molar mass of lactic acid using the atomic masses:
- Molar mass = (3 * 12.01 g/mol) + (6 * 1.01 g/mol) + (3 * 16.00 g/mol)
3. Convert the given quantity, 1.50 moles, into the number of molecules:
- 1 mole of any substance contains approximately 6.022 x 10^23 molecules (Avogadro's number).
4. Multiply the number of moles by Avogadro's number to obtain the number of molecules:
- Number of molecules = 1.50 moles × 6.022 x 10^23 molecules/mol
5. Determine the number of carbon atoms:
- In 1 molecule of lactic acid, there are 3 carbon atoms (C3H6O3).
6. Multiply the number of molecules by the number of carbon atoms per molecule:
- Number of carbon (C) atoms = 3 carbon atoms/molecule × (1.50 moles × 6.022 x 10^23 molecules/mol)
By following these steps, you can calculate the number of C atoms in 1.50 moles of lactic acid.
