Lithium Hydroxide, LiOH, is used in spacecrafts to recondition the air by absorbing the carbon dioxide exhaled by astronauts. The reaction is:
2LiOH(s) + CO2(g) -> Li2CO3(s) + H2O (l)
What volume of carbon dioxide gas at 218*C and 781 mmHg could be absorbed by 327g of lithium hydroxide?
Calculate the volume the gas will occupy if the pressure is increased to 1.87 while the temperature is held constant.
