The level of carbon dioxide in the air in a spacecraft can be controlled by passing the air through canisters containing lithium hydroxide, LiOH.
In a laboratory trial, the air in a 5.00 L container at 1.10 × 102 kPa and 25.0°C was passed through a canister of LiOH. The pressure of the air in the container decreased to 1.00 × 102 kPa, measured at 25.0°C.
The mass of CO2 absorbed from the air sample by the LiOH in the canister was
A. 0.89 g
B. 9.77 g
C. 10.6 g
D. 116 g
