According to the question,
CO2 dissolved in 1 cm3 is 0.8 mg or 8 × 10−4 g.
So, CO2 dissolved in 10 L, i.e., 104 cm3 = 8 × 10−4 × 104 =8 g.
Then, using PV = nRT

Human body has, on an average, 10 L of blood and each cm3cm3 of this ...
Given:
- Average volume of blood in the human body = 10 L
- Amount of dissolved CO2 in 1 cm3 of blood = 0.8 mg
To find:
- Volume of CO2 (at STP) that can be recovered from the human body on average
Solution:
Step 1: Calculate the total amount of dissolved CO2 in the body
Volume of blood in the body = 10 L
Density of blood = 1.06 g/cm3 (approximated value)
Using the formula: Mass = Volume × Density
Mass of blood in the body = 10 L × 1.06 g/cm3 = 10.6 kg
Since each cm3 of blood contains 0.8 mg of dissolved CO2,
Total amount of CO2 in the body = Mass of blood × Amount of CO2 in 1 cm3 of blood
= 10.6 kg × (0.8 mg/cm3) = 8.48 g
Step 2: Convert the mass of CO2 to moles
Molar mass of CO2 = 44 g/mol
Using the formula: Moles = Mass / Molar mass
Number of moles of CO2 in the body = 8.48 g / 44 g/mol = 0.1927 mol
Step 3: Calculate the volume of CO2 at STP
At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 L of volume.
Using the formula: Volume = Moles × Molar volume
Volume of CO2 at STP = 0.1927 mol × 22.4 L/mol = 4.31 L
Answer:
The volume of CO2 (at STP) that can be recovered from the human body on average is approximately 4.31 L.
Therefore, option 'A' (4.07 L) is the correct answer.
- Average volume of blood in the human body = 10 L
- Amount of dissolved CO2 in 1 cm3 of blood = 0.8 mg
To find:
- Volume of CO2 (at STP) that can be recovered from the human body on average
Solution:
Step 1: Calculate the total amount of dissolved CO2 in the body
Volume of blood in the body = 10 L
Density of blood = 1.06 g/cm3 (approximated value)
Using the formula: Mass = Volume × Density
Mass of blood in the body = 10 L × 1.06 g/cm3 = 10.6 kg
Since each cm3 of blood contains 0.8 mg of dissolved CO2,
Total amount of CO2 in the body = Mass of blood × Amount of CO2 in 1 cm3 of blood
= 10.6 kg × (0.8 mg/cm3) = 8.48 g
Step 2: Convert the mass of CO2 to moles
Molar mass of CO2 = 44 g/mol
Using the formula: Moles = Mass / Molar mass
Number of moles of CO2 in the body = 8.48 g / 44 g/mol = 0.1927 mol
Step 3: Calculate the volume of CO2 at STP
At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 L of volume.
Using the formula: Volume = Moles × Molar volume
Volume of CO2 at STP = 0.1927 mol × 22.4 L/mol = 4.31 L
Answer:
The volume of CO2 (at STP) that can be recovered from the human body on average is approximately 4.31 L.
Therefore, option 'A' (4.07 L) is the correct answer.
