The circulation of blood in human body supplies `O_(2)` and releases `CO_(2)` The concentration of `O_(2)` and `CO_(2)` is variable but on the average `100mL` blood contains `0.02 g` of `O_(2)` and `0.08 g` of `CO_(2)` Calcultate the volume of `O_(2)` and `CO_(2)` at 1 atm and body temperature `37^(@)C` assuming 10 litre blood in human body .A. `2 L, 4 L`B. `1.5L, 4.5 L`C. `1.59 L, 4.62 L`D. `3.82 L`, `4.62 L`

Answer» Correct Answer - C
`:. 100 ml` blood has `0.02gO_(2)` and `8gCO_(2)`
`:. 10,000 ml` blood has `2gO_(2)` and `8gCO_(2)`
Using `PV= nRT`
for `O_(2), 1xxV_(O_(2))=(2)/(32)xx0.0821xx310`
`implies V_(o_(2))= 1.59 Litre`
for `CO_(2), 1xxV_(CO_(2))=(8)/(44)xx0.0821xx310`
`implies V_(O_(2))= 4.62 Litre`
