Carbon dioxide made up of carbon and oxygeni.e. CO2
1 mole of carbon=12g
1 mole of oxygen=16g
Total mass=mass of carbon+2×mass of oxygen=12+2×16=44g
According to question
If 1 mole of CO2=44g
Then,22g of CO2=22/44 of mole of CO2
=1/2 of mole of CO2
1 mole of carbon=12g
1 mole of oxygen=16g
Total mass=mass of carbon+2×mass of oxygen=12+2×16=44g
According to question
If 1 mole of CO2=44g
Then,22g of CO2=22/44 of mole of CO2
=1/2 of mole of CO2

We are given that the sample contains 22 g of carbon dioxide and we need to determine what this quantity is equal to.
To solve this problem, we can use the concept of molar mass and Avogadro's number.
1. Calculate the molar mass of carbon dioxide:
- Carbon has a molar mass of 12.01 g/mol.
- Oxygen has a molar mass of 16.00 g/mol.
- Since carbon dioxide has one carbon atom and two oxygen atoms, we can calculate its molar mass as follows:
Molar mass of carbon dioxide = (1 * molar mass of carbon) + (2 * molar mass of oxygen)
Molar mass of carbon dioxide = (1 * 12.01 g/mol) + (2 * 16.00 g/mol)
Molar mass of carbon dioxide = 12.01 g/mol + 32.00 g/mol
Molar mass of carbon dioxide = 44.01 g/mol
2. Calculate the number of moles:
- We can use the formula: Moles = Mass / Molar mass
- Moles of carbon dioxide = 22 g / 44.01 g/mol
- Moles of carbon dioxide ≈ 0.499 moles
Therefore, the sample of 22 g of carbon dioxide is approximately equal to half a mole of carbon dioxide (Option C).
