Question

problem 8.82
during laparoscopic surgery , carbon dioxide gas is used to expand the abdomen to help create a larger working space
A) if 5.15 L of CO2 gas at 10 C at 783 mmHg is used what is the final volume in liters of the gas at 39 C and a pressure of 755 mmHg if the amount of CO2 remains the same.

problem 8.44
use molar volume to calculate each of the following
A) the number of moles of CO2 in 3.70 L of CO2 gas

problem 2
calculate the pressure in atmosphere of 1.66 moles of helium gas in a 10.0 L container at 24 C
problem 3

Explanation / Answer

8.82

A) moles of CO2 = PV/RT = (783/760) x 5.15/0.08205 x (273 + 10) = 0.23 mols

So volume of CO2 under new conditions,

V = nRT/P = 0.23 x 0.08205 x (273 + 39)/(755/760) = 5.93 L

8.84

A)

1) moles of CO2 in 3.70 L CO2

the volume occupied by 1 mole of any gas is 22.4 L

So the moles of CO2 in 3.70 L = 0.165 mol

2) Pressure = nRT/V = 1.66 x 0.08205 x (273+24)/10 = 4.045 atm of He gas
