We will calculate the density using the ideal gas law equation:
For the new conditions, the only given value is the final volume of the CO gas. We’ll have to determine the final pressure and temperature.
Assuming the amount of gas in moles (n) remains constant and R is also a constant:
Relate initial and final conditions:
V1 = 0.51 L V2 = 3.1 L
P1 = 1.5 atm P2 = ?
T1 = 312 K T2 = ?
We can now calculate the density of CO gas in the new conditions:
A quantity of CO gas occupies a volume of 0.51 L at 1.5 atm and 312 K . The pressure of the gas is lowered and its temperature is raised until its volume is 3.1 L .
Find the density of the CO under the new conditions.
