Yes, I can assist you with finding the molecular weight of 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone.
To determine the molecular weight, we need to calculate the sum of the atomic weights of each element in the compound. Here are the steps:
Step 1: Identify the elements and their corresponding atomic weights:
- Carbon (C) has an atomic weight of 12.01 g/mol
- Hydrogen (H) has an atomic weight of 1.01 g/mol
- Oxygen (O) has an atomic weight of 16.00 g/mol
- Ethyl group (C2H5) has an atomic weight of 29.07 g/mol
Step 2: Count the number of each element in the compound:
- 6 carbon atoms (C)
- 12 hydrogen atoms (H)
- 1 oxygen atom (O)
- 2 ethyl groups (C2H5)
Step 3: Multiply the atomic weight of each element by the number of atoms present:
- Carbon: 6 x 12.01 g/mol = 72.06 g/mol
- Hydrogen: 12 x 1.01 g/mol = 12.12 g/mol
- Oxygen: 1 x 16.00 g/mol = 16.00 g/mol
- Ethyl group: 2 x 29.07 g/mol = 58.14 g/mol
Step 4: Add up the weighted masses of each element:
72.06 g/mol (C) + 12.12 g/mol (H) + 16.00 g/mol (O) + 58.14 g/mol (ethyl group) = 158.32 g/mol
Therefore, the molecular weight of 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone is approximately 158.32 g/mol.
To find the molecular weight of 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone, you can use a molecular weight calculator or calculate it manually. I will explain both methods.
Method 1: Using an Online Molecular Weight Calculator
1. Open a web browser and search for an online molecular weight calculator. There are several options available, such as Chemicalize, PubChem, or Mol-Instincts.
2. Navigate to one of the molecular weight calculation websites.
3. Enter the chemical formula of 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone into the input box. The chemical formula for this compound is C22H21NO3.
4. Click on the "Calculate" or "Submit" button to obtain the molecular weight.
Method 2: Manually Calculating Molecular Weight
1. Start by determining the atomic masses of each element present in the chemical formula. You can find these values on the periodic table of elements.
- Carbon (C) = 12.01 g/mol
- Hydrogen (H) = 1.008 g/mol
- Nitrogen (N) = 14.01 g/mol
- Oxygen (O) = 16.00 g/mol
2. Count the number of atoms of each element in the chemical formula and multiply it by their respective atomic masses.
- C22: 22 (atoms) * 12.01 (g/mol) = 264.22 g/mol
- H21: 21 (atoms) * 1.008 (g/mol) = 21.168 g/mol
- N: 1 (atom) * 14.01 (g/mol) = 14.01 g/mol
- O3: 3 (atoms) * 16.00 (g/mol) = 48.00 g/mol
3. Add up the individual atomic masses calculated in step 2.
- 264.22 g/mol + 21.168 g/mol + 14.01 g/mol + 48.00 g/mol = 347.398 g/mol
4. Round the result to a reasonable number of significant figures. In this case, it could be rounded to 347.4 g/mol.
So the molecular weight of 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone is approximately 347.4 g/mol.
If you will type the formula in here, it will calculate it for you.
