Question

a certain mass of nitrogen occupies 700 cm^3 at a certain pressure. When the pressure becomes 2.8 atm it occupies 1400 cm^3. Calculate the initial pressure.​

Answer 1

Answer:

assume it to be an ideal gas and use ideal gas eqn

Explanation:

P1V1=P2V2

P1=2.8atm

V1=1400cm³

V2=700 cm³

P2=P1V1/V2=2.8×2=5.6atm
