Solutions Question 173
Question: Henry’s law constant K of $ CO_2 $ in water at $ 25{}^\circ C $ is $ 3.0\times {10^{-2}}mol,{L^{-1}}at{m^{-1}} $ . The mass of $ CO_2 $ present in 100 L of soft drink bottled with a partial pressure of $ CO_2 $ of 4 atm at the same temperature is
Options:
A) 5.28 g
B) 12.0 g
C) 428 g
D) 528 g
Show Answer
Answer:
Correct Answer: D
Solution:
Moles of $ CO_2 $ dissolved $ =K\times {P_{CO_2}}\times V_{bottle}=3\times {10^{-2}}\times 4\times 100=12;$
Mass of $ CO_2=12\times 44=528g $
