Number of gram-molecules means number of moles of O2 molecules Now, 6.02 x 10^24 CO molecules = 10 moles of CO (divided by 6.02 x 10^23) 1 mole of CO has 16 g or 0.5 mole of O2 therefore,10 moles of CO will give 10 x 0.5 = 5 moles or gram-molecules of O2 (oxygen) .

1 mole of co is equal to 1 mole of o so 6.02×10^24 of co is equal to 6.02×10^24 o..which is equivalent to 10 gram of oxygen atoms...and so oxygen is diatomic so o2=1/2×10--->5 grams... so It's a 5g of oxygen molecules....

The number of g-molecules of oxygen in 6.02 × 10^24 CO molecules can be calculated by understanding the stoichiometry of the chemical reaction and using Avogadro's number.

Stoichiometry of the Reaction:
CO is a molecule that consists of one carbon atom (C) and one oxygen atom (O). In a balanced chemical equation, we can see that one molecule of CO reacts with one molecule of oxygen (O2) to produce one molecule of carbon dioxide (CO2). The balanced equation is as follows:

CO + O2 -> CO2

From this equation, we can see that the number of oxygen molecules required is the same as the number of CO molecules.

Avogadro's Number:
Avogadro's number is a fundamental constant in chemistry, representing the number of particles (atoms, molecules, or ions) in one mole of a substance. It is equal to 6.02 × 10^23 particles per mole.

Calculating the Number of g-Molecules:
To calculate the number of g-molecules of oxygen in 6.02 × 10^24 CO molecules, we need to find the number of moles of CO molecules and then convert it to the number of moles of oxygen molecules.

1. Calculate the number of moles of CO molecules:
Given that there are 6.02 × 10^24 CO molecules, we can use Avogadro's number to convert this quantity to moles:

Number of moles of CO molecules = (6.02 × 10^24 CO molecules) / (6.02 × 10^23 molecules/mol)
= 10 moles

2. Calculate the number of moles of oxygen molecules:
Since the stoichiometry of the reaction tells us that the number of CO molecules is equal to the number of oxygen molecules, the number of moles of oxygen molecules is also 10 moles.

3. Convert the number of moles of oxygen molecules to g-molecules:
The concept of g-molecules is used to represent the number of moles of a substance. To convert moles to g-molecules, we multiply by the molar mass of the substance.

The molar mass of oxygen (O2) is approximately 32 g/mol. Therefore:

Number of g-molecules of oxygen = (10 moles) * (32 g/mol)
= 320 g-molecules

Therefore, there are 320 g-molecules of oxygen in 6.02 × 10^24 CO molecules.

In summary, by understanding the stoichiometry of the reaction and using Avogadro's number, we can calculate the number of g-molecules of oxygen in a given number of CO molecules.
