The average oxygen content of arterial b...

The average oxygen content of arterial blood is approximately `0.25 g` of `O_2` per litre. Assuming a body temperature of `37^(@)C`, how many moles of oxygen are transported by each litre of arterial blood and how many millilitres?

A

`7.8xx 10^(-3)" and "200 mL`

B

`6.8xx 10^(-3)" and "200 mL`

C

`7.8xx 10^(-3)" and "100 mL`

D

`6.8xx 10^(-3)" and "100 mL`

Text Solution

Verified by Experts

The correct Answer is:
A
The number of moles of oxygen per litre of blood is `(1mol O_(2))/(32g O_(2))xx 0.25gO_(2)= 7.8xx 10^(-3)mol O_(2)`
the volume of oxygen is, `V= (nRT)/(p)= (7.8xx 10^(-3)xx 0.0821xx 310)/(1)= 0.2L= 200 mL O_(2)`.
