Molar mass of O2 = 32 g mol-1
32 g of O2 = 6.023 x 1023 molecules
40 g of O2 =
= 7.529 x 1023 molecules
Mass of 6.023 x 1023 molecules of CO2 = 44 g
Mass of 7.529 x 1023 molecules of CO2
32 g of O2 = 6.023 x 1023 molecules
40 g of O2 =
= 7.529 x 1023 moleculesMass of 6.023 x 1023 molecules of CO2 = 44 g
Mass of 7.529 x 1023 molecules of CO2

Given:
Mass of oxygen = 40 g
To find:
Mass of carbon dioxide containing the same number of molecules as in 40 g of oxygen
Solution:
To solve this problem, we need to use the concept of molar mass and Avogadro's number.
Step 1: Find the number of molecules in 40 g of oxygen.
The molar mass of oxygen (O₂) is 32 g/mol.
Number of moles of O₂ = Mass / Molar mass = 40 / 32 = 1.25 mol
Number of molecules of O₂ = Number of moles * Avogadro's number
= 1.25 mol * 6.022 x 10²³/mol
= 7.53 x 10²³ molecules
Step 2: Find the mass of carbon dioxide containing the same number of molecules as in 40 g of oxygen.
The molar mass of carbon dioxide (CO₂) is 44 g/mol.
Number of moles of CO₂ = Number of molecules / Avogadro's number
= 7.53 x 10²³ molecules / 6.022 x 10²³/mol
= 1.25 mol
Mass of CO₂ = Number of moles * Molar mass
= 1.25 mol * 44 g/mol
= 55 g
Therefore, the mass of carbon dioxide containing the same number of molecules as in 40 g of oxygen is 55 g.
Answer: (b) 55 g
Mass of oxygen = 40 g
To find:
Mass of carbon dioxide containing the same number of molecules as in 40 g of oxygen
Solution:
To solve this problem, we need to use the concept of molar mass and Avogadro's number.
Step 1: Find the number of molecules in 40 g of oxygen.
The molar mass of oxygen (O₂) is 32 g/mol.
Number of moles of O₂ = Mass / Molar mass = 40 / 32 = 1.25 mol
Number of molecules of O₂ = Number of moles * Avogadro's number
= 1.25 mol * 6.022 x 10²³/mol
= 7.53 x 10²³ molecules
Step 2: Find the mass of carbon dioxide containing the same number of molecules as in 40 g of oxygen.
The molar mass of carbon dioxide (CO₂) is 44 g/mol.
Number of moles of CO₂ = Number of molecules / Avogadro's number
= 7.53 x 10²³ molecules / 6.022 x 10²³/mol
= 1.25 mol
Mass of CO₂ = Number of moles * Molar mass
= 1.25 mol * 44 g/mol
= 55 g
Therefore, the mass of carbon dioxide containing the same number of molecules as in 40 g of oxygen is 55 g.
Answer: (b) 55 g
