A gas occupies 175 mL at a pressure of 825 torr. What is the volume when the pressure is decreased to 415 torr?
The new volume will be
You will need to use Boyle's law to answer this question. Boyle's law states that when temperature is constant, the volume of a gas is inversely proportional to the pressure. This means that if the volume increases, the pressure decreases and vice versa. The equation for Boyle's law is:
