Blood circulation in human body provides

\mathrm{CO} 2

and emits

\mathrm{C}

\mathrm{O} 2

. The concentration of

\mathrm{O} 2

and

\mathrm{CO} 2

is variable, but on an average

0.02 \mathrm{~g} \mathrm{O} 2

and

0.08 \mathrm{~g} \mathrm{CO} 2

present in an

100 \mathrm{ml}

of blood. Find the volume of

\mathrm{O} 2

and

\mathrm{CO} 2

in human's body blood (Assume

9.5 \mathrm{~L}

) at

1 \mathrm{~atm}

and

37 \mathrm{oC}

body temperature .

View answer and explanation

Correct option: A

1.511 \mathrm{~L}, 4.396 \mathrm{~L}

Option A is correct because, using the ideal gas law and the given concentrations, the volumes of O2 and CO2 are calculated to be approximately 1.511 L and 4.396 L, respectively.
