Ga sample of o2(g) in a 3.0-l container has a pressure of 3.0 atm. if the container volume is changed to 6.0 l, what is the new pressure?

1.5 atm

Explanation:

In this question you have make some assumptions to solve this question:

The equation of ideal gas is:

PV=nRT

P: Pressure of gas

V: Volume of gas or container (as volume of gas is same as volume of container when gas is considered as ideal gas)

n: Number of moles of gas in container

R: Universal gas constant = 8.314 J/mole/K = 0.0821 L·atm/mole/K

T: Temperature

In this question n, R and T as considered as constant, only P and V varies.

The initial conditions are:

   .........eq(1)

The final conditions are:

   .........eq(2)

Since the right side of eq(1) and eq(2) are equal so the left side will also be equal.

Therefore,

overcharge is the right answer system
