Question 17

3 Points

Humpback whales have large lungs (volume 3.600 x 10³ L). If a whale taakes a full breath of air at the surface (pressure = 1.000 atm or 101.3 kPa) and the internal body temperature of the whale is 36.40 ^oC, how many grams of O₂ gas are in the whale's lungs? BLANK-1 (R = 8.314 kPa L K^-1 mol^-1; R = 0.0821 atm L K^-1 mol^-1 , give your answer to 4 significant figures)

Answer 1

Hence the answer of the question is 9073.2224 gm or 9.0732 Kg.
