We have to calculate the initial volume of a gas when a gas expands from a pressure of 1.60 atm to a pressure of 695 torr at constant temperature.
We will solve this problem using the Boyle’s law.
Boyle’s law states that the volume of a gas varies inversely with the pressure applied on it.
We can remove the proportionality sign to add “=” sign and a constant.
For two states of a gas:
An ideal gas at a pressure of 1.60 atm is contained in a bulb of unknown volume. A stopcock is used to connect this bulb with a previously evacuated bulb that has a volume of 0.810 L as shown here. When the stopcock is opened the gas expands into the empty bulb.
If the temperature is held constant during this process and the final pressure is 695 torr , what is the volume of the bulb that was originally filled with gas?
