There is an apparatus that consists of three glass bulbs connected by small glass tubes with the stopcocks closed. Given that the temp. is 27 degrees C, what is the pressure of gas in each glass bulb?

Question

Bulb 1-> 1L- 1.79gCO2
Bulb 2-> 2L- 0.162gH2
Bulb 3-> 3L- 4.87gAr

Answer 1

These all follow the general gas law which is PV = nRT.
To find n, use grams/molar mass. Don't forget to change T to Kelvin.
