To determine how many atoms are in the molecular formula C₁₁H₂₂O₁₁:
1. Understanding the components of the formula:
- C₁₁ represents 11 carbon (C) atoms.
- H₂₂ represents 22 hydrogen (H) atoms.
- O₁₁ represents 11 oxygen (O) atoms.
2. Counting the atoms:
- The carbon atoms (C) total: 11.
- The hydrogen atoms (H) total: 22.
- The oxygen atoms (O) total: 11.
3. Total number of atoms:
To find the total number of atoms in the molecule, simply add the number of carbon, hydrogen, and oxygen atoms:
Total number of atoms=11(C)+22(H)+11(O)=44
4. Final Answer:
The molecule C₁₁H₂₂O₁₁ contains a total of 44 atoms.
1. Molecular Breakdown
The formula C₁₁H₂₂O₁₁ corresponds to a compound with the following elements:
- Carbon (C): 11 carbon atoms
- Hydrogen (H): 22 hydrogen atoms
- Oxygen (O): 11 oxygen atoms
Each type of atom contributes to the overall structure and properties of the molecule. Understanding this composition is crucial in determining its molecular weight, chemical behavior, and interactions.
2. Types of Bonds
- Carbon (C) typically forms four covalent bonds because it needs four electrons to complete its outer shell. Carbon atoms in C₁₁H₂₂O₁₁ are likely connected to each other, hydrogen atoms, and possibly oxygen atoms.
- Hydrogen (H) forms one covalent bond, typically attached to carbon or oxygen.
- Oxygen (O) has six electrons in its outer shell and can form two covalent bonds (since it needs two more electrons to fill its valence shell). Oxygen atoms in the formula are most commonly found in hydroxyl (–OH) groups or as part of ether linkages (C–O–C).
3. Example: A Disaccharide
The molecular formula C₁₁H₂₂O₁₁ is very similar to the formula for disaccharides like sucrose (table sugar), which is made up of two monosaccharides: glucose and fructose.
- Sucrose (C₁₂H₂₂O₁₁) has one more carbon atom than C₁₁H₂₂O₁₁, but the formula you provided could represent a slightly different sugar, an isomer, or another carbohydrate derivative.
- In carbohydrates, the oxygen atoms are commonly part of hydroxyl groups (-OH) and ether linkages (-C-O-C-), which connect the monosaccharide units together.
4. Structural Implications
Each atom in C₁₁H₂₂O₁₁ likely forms bonds in a specific structural arrangement, and the number of atoms helps determine its:
- Physical properties: boiling point, melting point, solubility, etc.
- Reactivity: how the molecule might react with other molecules (e.g., in digestion, or as a food source).
- Molecular weight: The total molecular weight of C₁₁H₂₂O₁₁ is calculated by adding up the atomic masses of each element (Carbon = 12.01 g/mol, Hydrogen = 1.008 g/mol, Oxygen = 16.00 g/mol). This results in a molecular mass of approximately 342.3 g/mol.
5. How Atoms Are Arranged
In carbohydrates like this (if we consider it a sugar), the atoms are arranged in a specific configuration:
- Carbon atoms form the backbone of the molecule, with hydrogen atoms bonded to them.
- Oxygen atoms are positioned between carbons in certain configurations (like –OH or –O–).
- The arrangement dictates the molecule’s chemical behavior, such as how it can be broken down by enzymes (like sucrase in the case of sucrose).
6. Total Atoms: Counting Elements
We already calculated the total number of atoms in C₁₁H₂₂O₁₁:
- 11 carbon (C) atoms
- 22 hydrogen (H) atoms
- 11 oxygen (O) atoms
This leads to 44 atoms total. However, the structure and types of bonds formed between these atoms play a critical role in determining how the molecule behaves in biological systems, chemistry, or as a component in materials.
7. Molecular Weight Calculation
If we wanted to calculate the molecular weight of C₁₁H₂₂O₁₁, we use the atomic weights of each element:
- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.008 g/mol
- Oxygen (O): 16.00 g/mol
Molecular weight=(11×12.01)+(22×1.008)+(11×16.00)\text{Molecular weight} = (11 \times 12.01) + (22 \times 1.008) + (11 \times 16.00) =132.11+22.18+176.00=330.29 g/mol= 132.11 + 22.18 + 176.00 = 330.29 \, \text{g/mol}
So, the molecular weight of C₁₁H₂₂O₁₁ is approximately 330.29 g/mol.
8. Summary of Information
- The molecule C₁₁H₂₂O₁₁ contains 44 atoms: 11 carbon, 22 hydrogen, and 11 oxygen.
- It is structurally similar to common disaccharides like sucrose.
- Its molecular weight is about 330.29 g/mol.
- The carbon atoms are likely connected in a chain or ring structure with hydrogen and oxygen atoms forming hydroxyl (-OH) groups or ether linkages (C–O–C).
