Which of the following chemical formulas contains the most molecules?​

Question

5CO ​

3H2O​

2Fe2O3​

4C3H8

Answer 1

To determine which of the given chemical formulas contains the most molecules, we need to calculate the total number of molecules represented by each formula.

1. 5CO - This represents 5 molecules of carbon monoxide.
   Total molecules = 5

2. 3H2O - This represents 3 molecules of water.
   Total molecules = 3

3. 2Fe2O3 - This represents 2 molecules of iron(III) oxide.
   Total molecules = 2

4. 4C3H8 - This represents 4 molecules of propane.
   Total molecules = 4

Now, let's compare the total number of molecules:

• 5CO: 5 molecules
• 3H2O: 3 molecules
• 2Fe2O3: 2 molecules
• 4C3H8: 4 molecules

The formula with the highest number of molecules is 5CO, which contains 5 molecules.
