A small quantity of the inert gas argon is added to incandescent light bulbs to reduce vaporization of tungsten atoms from the solid filament. If the light bulb has a volume of 0.21L and a pressure of 1.30mmHg, what volume of argon gas is needed to fill the bulb at a pressure of 760 mmHg? Assume the argon gas temperature remains constant.
Just putting this out there for other students.
Answer: 0.0004L
The attached picture shows how I got the answer.
